That Daybreakers biggest problem is that there isn't enough of it should tell you enough: watching it provides short-term entertainment, but like those voracious bloodsuckers, it'll just leave you wanting more.
"Smartly constructed and lively all around, the gloom and doom submitted by filmmaking duo The Spierig Brothers is wildly entertaining and appropriately gushy with gore. Against all odds, Daybreakers is a blast."
Takes an idea that also happens to be a MESSAGE, in a genre that has been sucked dry, and still make something watchable. It's not the most brilliant vampire movie ever made, but it's the best one of 2010.
