Ok so I think your critique is fairly accurate from a feminist perspective but not at all from a cinematic perspective, meaning that you seem committed to criticizing these--fictional--characters for not espousing progressive, feminist ideology without paying much attention to whether the plot/tone/themes of the movie do. Especially with the Melissa McCarthy character, you take offense that most characters' behavior toward her in the movie is superficial and unfair, but doesn't that make the movie realistic? In the same way that Rose Byrne is wholeheartedly embraced for being beautiful and rich despite having terrible personal traits. The fact that McCarthy acknowledges her appearance and what that has meant for her, both humorously and seriously, and manages to be the only really caring/giving character out of the cadre of more conventionally attractive females is I think the bigger picture statement. We live in a discriminatory and backwards society and arguing that films should just ignore that i think misses the point of making films. Instead Bridesmaids embraces those conditions and shows how its characters manage to overcome that.
