That second star is for Stephen, who was the one character that made this monstrosity slightly bearable. Not that he's much of a character, but at least his particular brand of idiocy is the sort that draws a grudging smile out of a horror fan. He certainly has the best lines of anyone in the movie. A car in a horror flick that can only go forty miles an hour is a new one on me, and kind of funny.
Also mildly hilarious is the fact that the convenience store is clerked by a Justin Bieber look-alike.
Apart from that, there is absolutely nothing to see here. The gore gets points for being the right color, texture and coming with a minimum of stupid slurpy noises... it LOOKS better than average, but the killer and the director screw it up by not really seeming to understand how a knife is actually used. (But then, I like for the execution in excessive gore to make SENSE if at all possible--helps justify it. What can I say, I'm picky.) People who only care about the blood'n'guts bit will like it well enough.
The plot is virtually non-existent; the heroine, while not unlikeable, has no personality and is impossible to give a crap about; the acting is god-awful even by horror's already-low standards; the characters' decisions are stupid even by horror's already-low standards... and possibly worst of all, the final confrontation with the killer sickeningly reminds one of the one in "The House By The Cemetery."
Nasty... just nasty.
