It's like somebody heard of "Fury Road" - the amputee in the post-apocalyptic future - but never saw it, and thought to make their own version with mopeds, Mexicans, bad digital amputees..and the hot chick that wants to get with the cannibal that ate her limbs...
Bad. Really bad. They don't even bother to continue digitally removing the leg, just have her wear a prosthetic, and the missing leg varies from scene to scene. Starring Keannu Reeves who apparently has done nothing but eat twinkies since John Wick, and Jim Carrey as himself. Don't waste your time, life is far too short...
