O.K. so its a vampire movie which I like but looks like they didn't have time to elaborate whole story. End doesn't make sense it's cut rapidly.(hope there wound be 2nd part) There is no fully developed world of vampires. Whole movie could be based in total different reality, lets say during world war 2 or among 2 gangs in Mexico, and it would change character of movie. They didn't use vampires potential. Compare it with Underworld and You'll see what I mean.
