I just finished Ninja Assassin...

It wasn't near as bad as many reviews said it was, mind you it wasn't very GOOD but it was FAR from bad!

My two biggest complaints are,

#1: The "story", one of the reason I hate American movies is because they can't just have a fun cheesy movie, they have to try and disguise it as something else because we want to believe we are too smart to be entertained by a "stupid" movie.
So rather than have a quick sum up of a nice simple plot we end up with tons of flashbacks spaced out over time around a thrown together police plot as well, to take up more time so we have the illusion of a deep plot being delivered!

The thing they I guess they just gave up on trying to explain was why the police wanted to catch the ninja clan it was all WTF as this dude was claiming to be being "watched' by homeland security, and next thing you know he's leading the ...
...
Uh...I guess "The anti Ninja Swat team?" and there all shooting the crap out of the Ninjas so I was all like WTF yo!

#2: The "Special Effects", now I have no problem with "gore" in a movie but the blood in the movie looks almost humorous because it was SOOOO FAKE I mean they would CGI blood into a fight to the point it would look like Playing Mortal Kombat: Deadly Alliance or something, and it would be hard to really "get into" any of the fights because there would be so many "Little things" CGI-ed into the scene like wavy effects when swinging weapons or throwing Ninja stars, and there were so many effects done to the movement that even when a good fight would happen it would take away from the overall flow of the scene.
Also since it was an American director trying to appeal to an American audience they tried WAY to hard to make the Ninjas appear "Super natural" it wasn't TO prevalent but at times they would turn to mist which was like a "WTF" to me every time I saw it but the worst part was every time there would be a part where someone was sneaking around they would do this annoying thing where you could hear whispering going on which is usually an effect saved for ghosts and other supernatural things.

I was willing to let the Cheesy blood effects go because I mean how many old Kung-Fu / ninja movies had just HORRIBLE looking blood in them, but there was SO MUCH of it!

It gave a feeling like the director and writer wanted to a better movie, but like they were forced by their producers to make what they did

I DID like the fights when they got going though there was this one fight scene that was in the middle of a street with lots of traffic, and they were all getting hit by cars as they were fighting that was pretty baddass (I know it was mostly CGI but still looked pretty good) and the fact the last fight ended in a burning house it looked like a scene from Samurai Resurrection (A nice Sonny Chiba reference) was pretty cool.
Over all if you are willing to over look some story that make little since the movie's pretty good.

I would recommend RENTING it rather than buying it, because it's worth seeing once.
