You all don't get it
Its pretty clear that this movie is a dark comedy. The sharp contrast in mood and tone from the other 2 films is pretty obvious. I mean, the first one is well done, and most of us can agree. The second one is good in a different kind of way, like an arthouse surrealist flick like eraserhead. The only problem with the second one: Six tried too hard to outdo himself, and made the violence and gore seem cheap and Eli-Roth-ish. I think he realized that, and instead of cranking the knob on the third one, he'd just try something different. I'm pretty sure this movie is supposed to make you laugh and cringe, and realize that while the first two were actual attempts at serious filmmaking, this one can be the cult-status treat for the fans (see: Evil Dead 2).
I don't think I've ever laughed so hard in my whole life. The sheer (intentional) absurdity starts with the premise and setting alone. The second I saw Laser in a Texas ten gallon, with a big belt buckle, surrounded by American flags - I knew I was in for a satire or comedy. The over the top screaming and graphic dialogue was so unusual and overdone, there's no way it can be taken seriously, even by Six. I'm sorry if you guys wanted another "serious" installment to the series. I, on the other hand, will make this part of my horror comedy collection, right in between Evil Dead 2, Dead Alive, and Slither. If you sat through this flick without laughing once, I'm sorry, but you're missing the point.
