I've always liked Kristen Wiig. She's very funny and creates distinct supporting characters (Date Night, Knocked Up, Adventureland), but rarely is she the lead actress.
Thanks to Bridesmaids, that's all changed.
The film is a funny take on the whole maid-of-honor angle during weddings. Annie (Wiig) has been chosen to be the lead bridesmaid by her best friend Lillian (Maya Rudolph). But being in a tough personal and professional situation, Annie tries to do her best to come up with the best bridal send-off-- to humorous and awkward results.
You could feel the funny energy with the bridesmaids (all of them, with the exception of Rose Byrne, are comic veterans). The story has the requisite Judd Apatow gross-outs, but it's pretty tame compared to Superbad or The 40-Year Old Virgin. I guess the film was played out to appeal to the female audience's sensibilities.
Built more like a rom-com than a pure comedy, Bridesmaids that spreads out the humor and sprinkles it with romance and relationships. I think many women would feel that the film captures the stress in weddings and packages it in a funny way.
There's definitely no bridesmaid finish for this film-- it's a damn good chick flick.
