I haven't seen it yet and I'm usually reluctant to go and watch films if I sense they're too suspiciously hyped-up (just a pet peeve of mine), and especially after reading similar criticisms like X's online.

Apparently it also thrives on white guilt or colonial guilt (didn't one of the female characters call some white guy a "colonizer" or something?).
There was even a woman tweeting that she was going to wait a couple of weeks before watching it because she didn't want to spoil black people's "moment" with her presence. I know it's just an extreme case of whackiness but still, if that's the underlying theme of the film then it must be shit.

That and the laser-tipped bone spears.

I'll download it for 1.5€ when it's available for 1.5€.
