Although this is a very serious subject, the film does not make light of it in any way. Bullock is perfect in this role as the outrageous sister who's cake splattering antics ruin her sister's wedding. Buscemi is the 'seen it all' counsellor whom she has to fight to stay put, and although his part isn't huge, he's almost the sober voice of God in her struggle to become clean. However, if we're talking howls of laughter here, then the prize goes to the camp German guy, who was just so wonderful I can't begin to describe him. It's almost worth watching this just to see what he's going to say next. All in all - kind of predictable in places, but Bullock is so watchable, you don't want the film to end.
