The best comedies take the commonplace, everyday things and poke fun at them. With Bridesmaids, you have the rituals of an upcoming wedding - something that somehow resonates deep within a woman's psyche - as fodder for Kristen Wiig's sharp witted screenplay.
If the upcoming event was the entire focus of the film it would probably fall into the morass of so many Adam Sandler type films - comedy without a purpose - but here there is a much deeper story as Wiig's character spirals downward, repeatedly getting her tail kicked by life. This tale would seem to be at odds with the comic premise, however here it gives the film depth and makes the jokes and skits seem natural and unforced (for the most part), instead of the be all, end all, point of the film. It also gives the opportunity to examine life choices and goals from a woman's perspective, and while some of the characters are archtypes, they still provide ample opportunities to look inside what women want.
Wiig's performance here is a strong one, though some of her confrontational scenes seem a bit too "in your face", but surely you can't deny her comic timing and chops. There is a long extended scene that occurs during an airplane flight that shows off Wiig's comic abilities as both a writer and comedian - it is almost worth the price of admission by itself.
But the film isn't all Wiig, as there are strong supporting players as well, from Rose Byrne's portrayal of the lonely rich girl, to a tour de force by Melissa McCarthy as the female oddball, echoing Galifanikas in The Hangover films.
There are some incongruities here, as the start of the film where Wiig spends the night with her "F**K buddy" and then in the morning is asked to leave - which she does on foot... umm, she walked there? Or did he pick her up and then couldn't be bothered to offer her a ride home (he couldn't be that callous could he? I mean, she was not supposed to have spent the night, so ... he was going to kick her out in the middle of the night - yeah, thanks for the honey, hope you don't get mugged while walking home...).
But that's just nit-picking, and besides, it allows for a very funny exit scene with Wiig riding atop an electronic gate.
The film is a bit raw and potty mouthed, but really, the grosser moments are within the bounds of the film's tenor and not there for gross out effect. Especially funny is when one of the bridesmaids yells at her kids to "watch your F**King language!"
Of course as humor is so subjective, there are jokes that work and one's that, for me anyway, didn't. I felt that the one-upmanship that took place at the engagement dinner was initially funny, but went on a bit too long, and the extended scene where Wiig tries to get the help of her maybe boyfriend police officer by performing illegal driving acts was absurd and trying too hard - though I did smile at the lowrider pass.
Overall there is the story of a real person with real, raw feelings (though I couldn't help but think that Wiig's character forgot that the wedding ritual was all about her friend and not about Wiig - which was eventually pointed out by said friend). That there happened to be a very funny film built around Wiig's character is what gives the film its strength - a very solid effort.
