This sequel is an improvement over the first, with better special effects, a more interesting story--and best of all, Kate Beckinsale speaking as little as possible (she has to be one of the worst actresses working these days). Yet the basic story-- the sire of all the vampires wanting to free his brother (the first werewolf)--isn't filled with enough information. Just how he and his twin brother became monsters is never explained--and you don't know what their father is, other than an immortal. Also, it's constantly mentioned that Scott Speedman is the first vampire/werewolf hybrid, yet it's said that the first vampire is also a hybrid. ???Of course, the movie ends with another sequel in mind--and it'll be interesting to see where it goes from there.If you enjoyed the first UNDERWORLD you'll dig this, particularly with all the vampire man bat and the werewolf transformations.
