I thought the movie was ok. It had its scary moments. The boss vampire that could speak was lame and the others were just annoying. Especially when they scream. The kid vampire scared the shit out of me though.
I thought the ending was starting get interesting when the vampires were smart enough to cover up whatever happened to the town. But how it really ended was disappointing.

I guess thats one of the plot holes which was never explained.
And how was the dirty guy who got thrown into jail related to the vampires? How come the vampires didn't kill him when they went for the guy's brother and grandmama?
