After much anticipation, fans finally had their first opportunity to witness the Love Is Blind reunion on Sunday. Due to technical difficulties, Nick and Vanessa Lachey were only able to stream it to limited viewers online.

If you haven't seen it already, Blind Dating is an experiment in pairing people without them actually seeing each other. Couples spend hours in "pods," talking and building deeper connections without actually meeting.

1. Lachey’s comments about body diversity

Love Is Blind is a reality show centered on the concept that "love is blind," yet has come under criticism for lacking body diversity. Unlike traditional dating shows, Love Is Blind allows contestants to meet and fall in love without ever physically meeting; instead they are split into pods where conversations through walls take place to determine whether or not engagement occurs before meeting face-to-face to form couples and eventually marry each other.

One issue that provoked much discussion from fans was Love Is Blind's tendency to feature conventionally attractive singles, despite its stated goal of "open and honest." This was particularly noticeable among women; as reported by The New York Times, many participants on Love Is Blind matched conventional beauty standards; which can create problems for individuals who do not fit this mold.

Lachey suggested in response to backlash that insecurities might be contributing to Love Is Blind's lack of body diversity. She pointed out that she sometimes wondered whether some contestants did not pass past the first "pod" stage because they felt insecure.

Though many fans were supportive of her comments, others found them offensive and damaging. Some noted similarities to other shows which pathologize women with larger bodies such as The Biggest Loser.

Another fan noted that having to be thin can create feelings of inadequacy about sexual attractiveness for viewers who wish to find love, as Vanessa attempts to make people feel bad about themselves which can be especially hard for those struggling with insecurities or low self-esteem.

Vanessa's comments may have come as a shock, but they should not be disregarded. Reality television can sometimes fail to embrace body diversity - especially on dating shows intended to showcase it - yet Vanessa serves as a timely reminder that individuals don't necessarily need to meet standard expectations when it comes to beauty or desirability.

2. Lachey’s comments about having a child

At Sunday's Love Is Blind reunion, Vanessa Lachey asked the three couples onstage whether or not they wanted children. Her question felt awkward, making contestants feel like they were being pressured about this issue - especially as no singles were polled - they found this insulting.

Many fans took to social media to vent their disappointment with the hosts, some even calling them out as being "terrible hosts" and demanding they be fired.

Vanessa and Nick Lachey may have long held positions within the entertainment industry, yet are relatively inexperienced when it comes to hosting reunions. Although they emceed Miss USA 2018 and 2019 and co-hosted Netflix's reality show respectively, it remains difficult to judge their credibility as hosts.

Reliability has also been an issue, as evidenced by technical issues resulting in fans waiting an hour before watching the season 4 reunion show. Needless to say, viewers were disappointed and many have taken to criticizing both hosts.

Beyond technical difficulties, many segments of the reunion were unnecessarily confusing and disjointed from one another. A prime example is when Tiffany Pennywell and Brett Brown discussed their time spent in pods - it felt too dramatic and was drawn-out too long; though it was interesting seeing them discuss their relationship more seriously than before.

Irina Solomonova, Zack Morris and Bliss Poureetezadi made for an improved appearance, yet tensions quickly flared. Vanessa tried cross-examining Irina about her views on cheating but was so overwhelmed with nerves that she kept interrupting Vanessa instead of giving her enough time to pose her questions.

Marshall Glaze was also accused of making derogatory comments about Jackie Bonds, and this caused host Vanessa to become upset with him. While Glaze defended himself and defended his actions, fans took to social media platforms like Twitter in protest at how he was treated and by Vanessa interrupting them during their discussion - this led them to voice their displeasure about this situation.

3. Lachey’s comments about her relationship with Nick

Vanessa Lachey and Nick Lachey's wedding was long overdue, yet still had its challenges. It took them some time to fully comprehend what kind of relationship they wanted and identify goals for their future together.

In the meantime, their family life blossomed beautifully. Together, they welcomed three children - Brooklyn, Camden, and Phoenix. While this has brought great joy, the Lacheys still struggle with finding ways to love one another more deeply.

Netflix's The Ultimatum: Marry or Move On features six couples who must make an ultimatum decision regarding whether they will marry their current partners or move on with someone new, and as part of that show the Lacheys are opening up about past relationships as well as how Jessica Simpson's divorce has affected them both.

As seen on the first episode of their show, Nick and Vanessa offered an open dialogue regarding how their marriage and divorce have affected both of them. Though divorce was very painful for both of them, they discussed ways they managed to work through it and continue enjoying each other's company.

Nick and Vanessa have experienced their fair share of heartache and pain; so if they can overcome it, so can anyone else.

Vanessa recently noted in an interview that she does not allow her past to define her; rather, she embraces positive memories and concentrates on cultivating her current healthy relationship with Nick.

She has also shed light on her strained relationship with Helen Bondoc. Though they've been estranged for over 20 years now, Vanessa insists she never closed off reconciliation as an option and remains open to hearing Helen Bondoc's side of their tales.

Nick and Vanessa clearly share an unbreakable bond, even through some rough patches in their relationship. After 11 years of marriage they're continuously working to be their best selves as individuals and as partners.

4. Lachey’s comments about her personal life

Vanessa Lachey has experienced both highs and lows during her time as an MTV VJ and actress, particularly with regards to her relationship with Nick Lachey.

Fans know Lachey and Nick have been married for more than 10 years and share two sons, Camden and Phoenix. However, their marriage has seen its share of problems over time.

On a recent episode of their reality dating show, The Ultimatum, Vanessa and Nick revealed some of the challenges they have been experiencing within their respective relationships. Vanessa mentioned how Nick's divorce from Jessica Simpson affected their path toward marriage but decided they could still move forward together.

Though their divorce had a lasting negative effect on them, she sees how it has given them some perspective and helped shape them into stronger, more mature people.

Vanessa remains committed to her family and career despite the negative comments on social media, serving as an MTV VJ while maintaining an acting career that is flourishing.

Mom to two sons Camden and Phoenix who were born in 2006, she recently welcomed daughter Brooklyn as her second child. Reuniting with them after many years was another special treat!

Though Lachey has found considerable professional success, she still faces considerable personal struggles from time to time. Following Phoenix's preterm birth and their subsequent divorce proceedings, Lachey found herself raising their son on her own for two years; additionally she and husband Nick went through some turbulent patches during this time period.

Issues surrounding Vanessa have surfaced during the Love Is Blind season four reunion. Many fans took to social media platforms such as Twitter to voice their displeasure with her questioning contestants regarding their baby plans.

Others found her too biased against Marshall Glaze and Paul Peden, with accusations that she gave Zach Goytowski too hard of time for defending Paul; additionally, she kept asking about their child plans.
