I got tricked by the trailer of this movie into expecting more than I got. I should've known better. The first movie was mediocre. So is this one. Mainly because it didn't make any sense. I'm too lazy to explain why in detail, but let's just say that the whole thing about swapping powers, which isn't even explained, isn't handled with any kind of logic. And (huge spoiler) if the Silver Surfer could destroy the Eater of Worlds, why didn't he just do it long ago, making the noble sacrifice and saving his own world in the bargain? (End of huge spoiler.)
And what is up with Mr. Fantastic's hair? I couldn't tell from one scene to the next where the gray was going to be. Sometimes it just went away altogether.
There were a few funny lines, some of the action was okay, but a lot of the special effects were right out of the cheese factory. I can't really recommend this one, but it has one thing going for it: It's short, only about 90 minutes long. There's something to be said for that.
