Having seen this one in the theater, I knew the story going in. Basically its a story of breaking down racial barriers in the 60's.
Its a fun story, but what makes it a curiousity and bizarre for me is John Travolta playing Edna Turnblad. As in the the theater, this position as the lead character's mom, is played by a cross dresser. But to see Travolta singing and dancing in this role is surreal. And when Christopher Walken comes out as Travolta's wife and is seducing him, that is really over the top making it worth seeing just for that.
This movie is way down on my summer movie list, but it was worth catching on my last long flight.
