Unrealistic and Stupid Plot

First we have a guy who lives in the jungle like some kind of Tarzan with no shirt, no shoes, and no shelter. There is a farm out in the middle of nowhere with no roads, no animals, no vehicles, and no neighbors. A band of outlaws who kill and kidnap at will with no resistance from the police and army. Tarzan could have killed some of the bad guys earlier, but kills them later. The whole movie was idiotic!
