I thought this movie was pretty great. Very entertaining and definitally worth seeing if you're into action flicks. And as could have been expected, it's got a good dose of originality and variation, ie. Lucy Liu's past in anime-style. The fight scenes were fantastic and the soundtrack was absolutely awesome... maybe even worth buying. Some parts of it dragged a little bit, but overall I thought it was worth it to see in the theatre. At least catch a matinee of this one! Unlike most, it won't be as good on rental.
On a side note, the hosing blood was LOL-tastic
