great success for a few reasons: the film shows the true comedy, emotions and insecurities that all women feel when their friends are getting hitched, it does an amazing job of dealing with the entire eclectic mix of women that get introduced (and keeping them distinctly original and separate in character), and Wiig's performance, which is both emotional and physical, is one of the most honest I've seen in a comedy. Above all, Bridesmaids solidified my thinking in that most weddings (and more specifically wedding planning)--no matter the who/what/where--bring out the worst in people.
Wiig portrays a girl named Annie, whose cake shop has gone under since the beginning of the economic recession. She's been best friends with Lillian for years and years, and they get together often to drink wine, read Us magazine and talk about how weird penises are, especially when a man rests them on their face while sleeping. Annie's also involved in a one-sided relationship with Jon Hamm, who beautifully plays a rich, douchey, even more sex-obsessed version of Don Draper. She's down on her luck, stuck in a limbo of emotionless sex and a dead-end job at a jewelry store (the setting for some great scenes due to her brash honesty about relationships and friendship to love-drunk customers). What could be Annie's rock bottom? That is a question that constantly gets raised and then one-upped throughout the film, starting with her best friend Lillian's engagement.
Back to Wiig: the movie is great because of her. Yes, there are many highlights from the other members of the bridal party, but they are usually a little more obvious and over-the-top than Wiig's honest and insecure performance of a woman who feels left behind in a world of successful careers and loving relationships. The key is that both men and women can relate to her plight. Every human experiences some form of jealousy and self-consciousness during major events (like a wedding), and sometimes we just want it to be over and done with. And although, as the film reaches a higher and higher minute in runtime, the movie does subscribe to some of the same old tired tropes that many women- or wedding-centric films rely on (specifically Wiig slowly realizing she wants a sweet and generous man instead of just a misogynistic fuck-buddy), Bridesmaids puts smiles on faces and warmth into even the most skeptical of hearts.
