"If you want actual burlesque, there is no shortage of annoying fat girls in dumb costumes jiggling to horrible songs all over Portland." wow, that's just really unnecessary, and also untrue. Being a dick does not automatically make you seem clever. This is a discussion forum not a middle school bathroom stall. I know that it's sort of the norm for people to hide behind the anonymity of online comments to unleash their assholism (before I get a "No shit Sherlock!") but that doesn't make it any less disappointing.
If you're gonna name a movie "Burlesque," then yeah, it should resemble burlesque, it's like naming a movie "Tennis," then showing ping pong. The only people who are going to want to see this movie are going to be people who are into dance so of course they're gonna care. When I wanna geek out on a hip hop movie I don't rent Dirty Dancing.
