- Angst? What Angst?: Allison doesn't seem all that broken up about all her friends being killed. Granted, they were pretty much all assholes.note
- Crosses the Line Twice: The film has a bunch of well-meaning, but misguided college students killed in horrific manner, played for laughs.
Tucker: (Having just switched off the wood chipper after one of the kids jumped in it, with only his legs remaining) "You okay?"
- Ho Yay: While Dale and Tucker are apparently neither gay nor in a relationship, it is implied that they might be Friends with Benefits. After all, it is pointed out very clearly that their cabin is far off from civilisation, that they planned on going there alone... and that the cashier loudly reads out that they - along with tools for fixing the cabin - purchased lubricated condoms. Of course, the list does include odd items like menstrual pads, which, like condoms, have other utilities (such as serving as waterproof covers for firearms), so it's hard to pin it down definitively. Though it's not helped with lines like this happening in the same scene as the officer stopping them.
Tucker: He's been strikin' out with the ladies, I figure a little man-time might do him some good.
- Moral Event Horizon: Chad crosses it when he kidnaps Allison and straps her to a Conveyor Belt o' Doom.
- Also the Memorial Day Massacre obviously enough is this for the maniacal hillbillies.
- Nightmare Fuel:
- Mitch's death via tree branch, while initially funny, becomes quite disturbing for some with the following scene.
- With all the references to rape and brutal murder sequences, the flashbacks showing the Memorial Day Massacre are rather out of place in such a light-hearted film, feeling more like one of Wes Craven's early works, The Last House on the Left or The Hills Have Eyes (1977).
- Some Anvils Need to Be Dropped: The film, rather violently, drops one about prejudice and not letting your fears overwhelm your judgment, coupled with a liberal dose of how Poor Communication Kills.
- Special Effects Failure: The CGI bee that lands on an impaled and dying Mitch is pretty unconvincing.
- What an Idiot!:
- Almost all of the college students, obviously.
- Dale is such a passive nice guy that he advises taking the safety off to a kid who wants to shoot him.
- Allison has difficulty parsing the gravity of the situation around her. Then again, she might just be in shock.
- The Woobie: Dale.
- Mitch, the college student who got himself stabbed by a branch, can be this to some viewers because he's one of the more level headed students and is still the first to die.
