Just got back from it. I wasn't expecting it to be very good, so I wasn't disappointed that way. Lots of flash, lots of special effects, no discernible plot, but a lot of hoopla. In many ways, my feeling from watching the teaser bits remains: it equals League of Extraordinary Gentlemen in that this film had lots of potential, all of it wasted.
I bow my head to the horror movies of the 30s and 40s that were so shamelessly ripped off.
My buddy both enjoyed it more and had more to gripe about; he has apparently read the comic book, which I didn't even know about. I couldn't keep up with half the things he said "just weren't right", but he is also a special effects nut and was drooling over several new effects types being used in the film.
