I liked it better than the book.
I know I'm going to be bashed for saying but before you start calling me a dumbass, hear me out. The book is my favorite book. But, I think it was Christina Ricci's performance that made me like the movie better. I know that's not a good reason but, it's the reason I'm giving.
Also, it's a lot closer to the book than the "Girl, Interrupted" movie was.
