Has anybody seen Daybreakers?

There is disturbing violence in some R movies but the gore in this movie is vampires eating blood (nothing that bad). If you liked I am legend or if you like the Underworld movies then you should check it out. I am not saying it is the greatest movie ever made but I liked it. On a side note the vampires if this movies have some yellow like eyes while in Underworld if I remember correctly they are a deep blue. I guess now popular culture has made vampires have different eyes then humans?
