Nuzi didn't ruin the show

I've been surfing on social media and I've found some people hating on Nuzi cuz:

1- It somehow ruined the show.

2- It retconned the whole show.

3- It didn't allow any character development for either N or Uzi

4- Both sides are supposedly kids even though they're teens

Am I in the wrong for adoring this ship and thinking that V was toxic and abusive to N despite caring about him and that's why he abandoned his crush on her and started dating Uzi?
