It's mostly just sad - not because Roth takes such a sharp scalpel to the social justice movement, but because he swings a baseball bat, and misses by a mile.

Flat-pack acting, frat-boy screenwriting (the portrayal of activists is spitefully dumb) and retro gore combine with smug throwback neocolonialist racism and unfunny jokes about diarrhoea, dope and Scooby-Doo.

es, Roth's film has its expected moments of high transgression, but you can never get away from the fact that all these references have been attached to the most hackneyed teen slasher narrative imaginable.

It’s still enjoyable to watch, but I can’t help but roll my eyes a bit at the way the tribe is depicted as the most evil, bloodthirsty killers imaginable.
