Just to be clear: Half of my 3 Star rating is because Kate Beckinsale is so gorgeous and talented. The other half of the rating is for the film itself.
The first word that comes to mind for describing this movie is: "disappointing". I thoroughly enjoyed "Underworld", the first movie in this series, and was looking forward to seeing this one.
I didn't dislike this film but I would hesitate to recommend it.
Did I mention how great Kate looked in black? :-)
