During the show someone in the audience asked about the similarities between this film and Tango and Cash. For me, I thought it was more similar to Return of the Jedi:
1. Good guys are an incesty love triangle with a guy, his long lost sister, and a buddy that he starts out not liking but end up bromancing.
2. Bad guy was left for dead, picked up by the really bad guy and built into a half-man, half-machine terminator dressed in black. Reports to some god-like entity, but is the clear number two guy.
3. Final battle has good guys luring bad guys into a battle against locals that use primitive weapons and knowledge of local landscape to defeat an army with much superior firepower.
