OK, just got in from seeing this one.
Overall, I liked it, its got that lad who played Kyle Reese in "Terminator 4" in it, along with Colin Farrel and David Tennant.
Wasn't too sure about Farrel's vampire character though, seemed a bit too "quirky"?
Then there was David Tennant's character, who was basically, playing it as David Tennant (or rather, a drunken David Tennant). Though admittedly his character did seem to have all the best lines.
Good fun, but being "old school" I think I liked the original 1985 film best out of the two. But don't let that put you off, see it and decide for your self.
Anyway, here's the trailer...
