Chamber of Secrets. Well, when it came out, I thought it was considerably more exciting than the first. These days, I can take it or leave it.
I enjoy Kenneth Branagh. It's a funny role for a guy who has made a career being pretty much as pretentious as possible. And in retrospect, with an eye toward Horcrux lore, it lays some interesting groundwork. I also like Christian Coulson as Tom Riddle. I wish they would have used him in Half Blood Prince. But my general feelings toward Chamber of Secrets are quite lukewarm.
In fact, I think in the Harry Potter film franchise, this one is weakest. It's a long, winding story and the trio runs into a lot of dead ends. Aragog is a dead end. The Polyjuice Potion is a dead end. Dobby randomly tries to kill or maim Harry a few times but to no real end.
Three is a big step up. Can't wait to talk about that one!
