The premise of the movie is really out there. Of course it's supposed to be over the top and even the explanation you get somewhere in the movie, why this is all happening is so crazy, that you can't help yourself but laugh about it.
Having said that, the sole and main reason, you are going to watch this, is the "bloody mess" it delivers (no pun intended). And it delivers on that premise, so if you are splatter fan, than you can pretty much enjoy this. Not that much going on in the acting category and or the story department. Based on a Cohen movie (which I haven't seen), it's pretty much everything you can expect from it.
