Good, not great. This was a solid action movie, a very average vampire movie, and a poor comedy movie.
Sure, the cgi wasn't perfect, but the action and especially the violence delivered.
The vampire rules were a bit confusing, but lately that's par for the course.
The biggest disappointment, however, was the lack of comedy. Considering the talent involved, this could've been the 'Shaun of the Dead' vampire sequelish movie we never got.
It's worth a watch, but you won't be blown away.
