I'm not a fan of Neil LaBute. I find his characterizations distasteful, and he seems unable to find a redeeming quality in any of his male protaganists. This play is no different.
Tom is a meely-mouthed, twenty-something account executive who falls in love with an obese librarian, named Helen. When his co-workers find out, they tease him mercilessly. Just when you think he has gathered up the strength to stand up for his woman, he falls prey to peer (societal) pressure. What makes it even worse, is that Helen, who had been very accepting of her own size throughout the play, becomes this pitiful fat girl who begs Tom to take her back. She even promises to get skinny for him. Why couldn't it have been a totally uncliched ending, and have Helen be angry and gutsy instead of weepy and begging.
