How bad is it? It's okay (damning with faint praise).
Should you see it? Yeah, but don't go out of your way.
This film, like "Zombeavers" and the short "Kung Fury" got a ton of social media coverage, but it - like those others - is no big deal. An alcoholic cop finds out he's a werewolf. It's meant as a horror comedy, but it's not scary (though the gore is much better done than usual for films I watch) and the laughs fall flat. It doesn't really go anywhere and it knows what it is: an attempt at making a cult film. It's, if anything, too serious.
