I don't get this movie, really, I don't. It's a remake of Eli Roth's debut, which was made using the same script, so it is pretty much the same movie plus blood minus weirdness. It is populated by moronic characters, awful dialogue and a shit load of cliché, it has every single cabin in the woods trope you can think of and it's not even self aware of funny.
Take The Evil Dead remake for instance. That movie gave up all the comedic tone of the original and replaced it with tons of gore and blood. Cabin Fever also abandons the weird style of the original, but it adds nothing in return. It's so bland and dull I can't even hate it.
