This was my type of film. Non stop action, interesting and believable martial arts scenes and other aspects I won't mention because they could be spoilers.
I found the story realistic and believable. I felt the lead actors were excellent. I was really impressed with Rain. I had never heard of him before this movie. When I researched him I found out that he was in Speed Racer (I have the DVD, but had not watched it)and so I watched the movie and enjoyed his part in that one also. I can't figure out why the major critics didn't give this movie high marks, however several critics mentioned that NINJA ASSASSINS is redundant leading me to believe they didn't understand the movie at all. The lead character is a NINJA who kills other NINJAS and other NINJAS are trying to kill him.
