Okay, so, call me crazy, but I think the implication that Carrie cheats on Big actually makes me more excited about Sex and the City 2:
I know, I know. But I disliked narratives where Carrie is wronged. The show and the movie are more interesting when the characters are in pickles of their own making: Miranda sabotaging her potential and then actual relationship with Steve, Samantha cheating with Richard and getting forgiven for it and realizing the whole thing means something, Charlotte working her way out of her disastrous and impulsive marriage. Superheroes have to have flaws, not be victims.
