Kevin and Vicky were an Annoying Couple
I thought their relationship and their characters got annoying fast. Kevin was always getting emotional and making a big deal out of dumb stuff like making everyone swear dramatic pacts and getting upset when random house parties weren't as magical as he had hoped. Vicky spent the whole movie trying to make her generic high school relationship mean more than it really was. She was constantly trying to coerce Kevin into saying that he loved her, when it was clear that he felt uncomfortable doing so and felt that his relationship with her was not as deep as she wanted it to be.
Dumb gripes, I know, but I've never really liked those two characters in any of the movies they show up in. Theyre that annoying couple that pretend like they are soulmates and have the deepest relationship in school, but they are constantly getting in fights and breaking up.
