This movie went in a direction unexpected. I did not know anything much about it. I thought is was going to be funnier based on trailer. But, I watched it and was entertained. That is the point of watching any movie! Somethings aren't realistic but we are talking about a vampire movie.
Reviews seem overly critical.
People it is not a documentary.
I did feel it was better than The Werewolf with Anthony Hopkins whom I really like as an actor. If you like vampire movies and pretty light horror movies that aren't ridiculously graphic. And, you aren't overly critical. You will probably like it okay.
