Vampires are attacking the world, and a group have to protect themselves in a house out in the country. Before the breakout, a man arrived at the house, and later showed himself to be a vampire. He is offering them a deal - if they help him survive during the days, he helps them survive during the night against vampires.
There has been a decreased number of vampire horrors lately, and the last one I can remember being watchable was probably "30 Days of Night" (minus the ending). We're in a different time now, so the priority is neither vampires that are powerful Counts, nor beasts. Much can be said about the current state of vampires and zombies alike, but it has been said before. "The Caretaker" decided to bring back the monsters in vampires, but is it enough?
Set out in the country, a small group of people are forced to hide in a mansion when ill people start turning into vampires. The first man to arrive at the place was a supposed doctor, there to help a man's sick wife. But it later turns out that he is one of them - a vampire. He went there to propose an offer to the humans: he'll protect them from the vampires if they protect him from humans in return. An offer they hardly can refuse, but soon there are small cracks within the group.
Personally I quite enjoyed the idea of the offer, it was that little extra that you'd need in a movie like this. Otherwise it would just have been a movie about vampires attacking. The movie is suffering from a few other things, however. First of all, I am a beliver that vampire movies should be heavy in atmosphere: there is a reason why they are night creatures. I don't need the movies to be scary and I am perfectly fine with a simple plot with a small twist like this one - vampires attacking. But there is nothing that really makes me feel that these are vampires. They can't be in the sun, but other than that I didn't feel it. It felt more like they were a horde of zombies, something I have grown tired of. Using the elements of the night more could possibly have improved it.
That said, it doesn't make the movie terrible, just not something special. The idea of the "offer" quickly runs out of intrigue and it goes back to the basics again. What the audience is left to look for then is the quality of the action at hand: the gore especially. It doesn't stand out as spectacular effects, it's just there. You're glad it's there, but it's something you might not even react to. The vampires are about as standard as they get, and if that's negative or not is up to you: fangs, bright eyes and often blood around their mouths (I wonder why? Oh.. right).
At times it's fairly interesting, at other times really bland. There are some parts that come off as trying to giving a more action hero-vibe to the "main" vampire, but it doesn't really give much effect. The vampire action works but it's not enough to carry the movie. It's a movie that some people will like and others won't because there are no real stand-outs in either the good or bad. What you get is another horror movie trying to show something about humans by throwing them in a house, while a generic monster is attacking.
