Here is a funny review that was on imdb.com , he also give it the maximum amount of stars :
The Vin Diesel, Hit-man, Explosion Movie, we have all been waiting for!, 27 August 2008
Author: h-longbaugh from United States
Let me just say, that they did it again! Cinematic GOLD! I saw this movie a few days ago and it's been on my mind ever since. I am telling everyone about it! Vin Diesel dives deep into his soul to pull off his role as a hit man who is a real tough brute even though you can tell there's a little something that may hint at him not being such a bad guy after all. He just does what he's paid to do which is to cause explosions and kill people. And THEN EXPLOSIONS ENSUE! and he has to take this girl to bad guys but realizes he shouldn't and then has to protect her which makes for some really good character development. There's also some really revolutionary slow motion action scenes WITH EXPLOSIONS and ROCKETS! And man, the soundtrack is so awesome. The theme song which is in the trailer perfectly original and not from any other movie ever. THEN EXPLOSIONS!
