Sure the movie may borrow from likes of The Matrix, The Crow, Blade, Dark City, etc, but the bottom line is it that it's very entertaining. I thoroughly enjoyed the film. I really don't understand why most critics have bashed Underworld. I loved the plot, the action, everything. I really liked the fact that is very dark, and serious. No stupid character is thrown in this movie for comic relief. I found the story to be original in it's own right. Kate Beckinsale did a great job. She's a very believable female action star, unlike those who will remain nameless (who would of thought). I look forward to the sequel.
