I really enjoyed this movie, too. Maybe a 8/10.
It was fast paced like some of you guys said, but it was an action movie. If it slowed down a bit, then it would of got boring for me.
Only thing that made me said "What?", was at the end. With all the special effects in the movie, Yukie had no signs of any damage.
(Hope that didn't spoil it for you guys that have not seen it.)
