Well, I watched this movie tonight and cried a lot. I thought it was pretty good, for the most part (yeah, the parts where she was upset or mad or hurt and went and ate will probably make fat-phobes think all fat people do that, but they think that already anyway). It was also a little predictable, but I don't know if that's because I'm older and have lived through a lot of the same crap so I could see where the movie was going and what was going to happen in future scenes. I did like the mother's co-worker and what she had to say about accepting oneself. And the store where Maggie shopped, and the owner's opinions about clothes (she said the average size for American women is 14, so you'd think manufacturers would make jeans that fit them) was totally awesome. There was a lot in there that advanced acceptance, not just fat acceptance, but for geeks and misfits of all kinds. And I thought the girl who was supposed to be homecoming queen and lost out (she voted for Maggie) was pretty neat too, there at the end, when she was talking about being seen only as the "pretty" girl and now people would have to see other things in her besides just the "pretty".
I'm thinking I really like Nikki Blonsky. I watched "Hairspray" the other night too, and thought it was pretty good. Yeah, I know some people have a problem with John Travolta in a fat suit, but I thought he did a pretty good job of it. There were a couple of scenes where it was pretty obvious that it was a fat suit, but there were also quite a few where he actually looked like a few fat women I've known, size and shape-wise. Again, there were scenes where food was used as comfort, stereotypical though it is, but it didn't seem to be for comic relief (and there was one scene where Edna was upset, went to eat something for consolation, and didn't. Not that that makes up for anything, but still......).
I think both of these movies ended up being pretty size-positive for the most part. Yeah, there were parts that could have been done better, but with the state of the OMGOBESITYEPIDEMIC!!!1!!!, the fact that they were done as well as they were is a good thing (to paraphrase Martha).
