I actually don't mind it not making sense. The preview showed that time paradoxes would be involved, and I like that kinda crap even when it doesn't make sene, so I was all geared up for that. And that element was fun.

I just felt, as I often feel at romantic chick type movies, that neither of the leads had much personality, or anything really special about them I could identify with or love, and that there was really no reason for them to be in love with each other, because I don't see what special thing they gave each other that other people couldn't. I just have a problem with that; I like love stories where I feel like the characters have something new and original to offer each other.
