Reviews for the movie are pretty heartening. I was a little nervous this would suck, but I believe that in spite of controversial views, the film adaptation of OSC's most popular book is bound to be pretty successful.

JEDIT: As I suspected, though, its difficulty in translating to film. I never expected it to be as enjoyable or deep as the book, and it looks like I may be right. I just want it to be enjoyable.
