The movie is almost to clever for itself. Breaking the 4th wall very early on, it still tries to be a "relatively" normal movie. It's a parody of course, but as it is very self-aware and self-conscious, the jokes are hit and miss.
It's a nice change to have a woman being in the lead role, in a movie like this, but in the end, even that joke is worn off, pretty quickly. It's actually pretty silly and you can have a lot of fun, if you stop thinking about a few things. So just try to enjoy it if you can and not see the many mistakes/flaws the story has. A funny horror movie that dares to be bloody and funny at the same time then ...
