Damn, isn't this movie almost a year old, richard, and you're now just talking about it?
joking aside, I thougt Underworld was a great movie. Good cast(Kate Beckinsale, she's hot), good special effects, and overall good story. The werewolves were ok, seeing that I saw Van Helsing(which is now the new benchmark in monster-comparing special effects). I enjoyed the plot, and in the end, I liked how what's his face became a hybrid. See this movie if you haven't already.
