Harry Potter and the Chamber of Secrets 3

I've never read any of the books, and was talked into going to the first movie by a friend of mine. I was quite surprised at how much I liked the first one, so I was eager to see the second. Never made it to the theater, but bought the DVD fairly soon after it came out. A little disappointing, but I think my expectations may have been higher than they should have. I like the kids they cast for the movie, I just wonder how quickly they will out grow their roles.
