It sucked. Really, the only thing they managed to get right was the Surfer. Every scene with him was wonderful. Everything else was piss-poor.
Julian McMahon's Doom is a pathetic second-rate Green Goblin. Dr. Doom was the inspration for Darth Vader. He should act it. McMahon was practically playing his character from Nip/Tuck in this movie (just as he did in the last). There is nothing menacing or threatening about Dr. Doom in this film. Nothing. While he looked the part, he simply didn't act it.
And Jessica Alba had some of the worst wigs I've seen since the first X-Men flick.
