narcissistic 20-30 year old who dreams obsessively about her "big day" then this is the movie for you! I have rarely seen a good movie about pre-wedding shenanigans but I enjoy so many of the cast members I thought I'd give it a shot. What a waste of $10! My synopsis: "Coked up, insensitive, mean girls ruin lifelong friend's rehersal dinner and then tramp around NYC trying to get laid and more coked up all under the pretense of getting their "friend's" wedding dress fixed (that they tore while mocking her size). In the end the selfish girls find boyfriends, get the dress fixed at the 11th hour and are forgiven by the kind, fat bride." I didn't care at all about these horrible, selfish characters. I'm a liberal person but constant use of the word "retard", glorification of cocaine use, mockery of overweight people, and celebration of cruelty and selfishness left me absolutely cold. What did I miss? I don't get all the five start reviews at all.
