This could have been a great movie...
I loved it from the start, as it had quite a dark atmosphere. But it kinda lost it later on - from when the dad and sister find them at the motel - wtf? Isn't the US quite a big place? The chances of that are exceptionally slim, like millions to one. I really hate it when they do that in movies, it's lazy writing to have such huge coincidences. And this was a group of people who are experts in disappearing, as they have been doing it for years, so there's no way his dad and sister could have tracked him. So they just bump into them in a random motel...
And that was at night wasn't it? So how did they escape out of the room? By opening the door and sunlight hurt the vampires, then somehow the dad, sister and Caleb teleported to the inside of the van and drove away. Lazy writing again, as they changed it from night to day, and because they somehow managed to escape from a room full of superhuman vampires.
And when he killed Severen with the truck.. that was just silly. How did it explode? It just went boom! for no apparent reason. Was it a truck full of grenades?
Still, it was good to stumble on this movie, some parts of it were awesome. I just feel that it fell apart later on.
