You know what you get when you cast a guy that looks like he still gets the crust cut off his peanut butter and banana sandwiches? Believability mother fucker, that's what. Remove the Bangbros logo and scatter a few Star Wars Amibos in the background and I would have defended it's authenticity until the end of time.
This is from the 1976 classic Water Power. It's a lot like Taxi Driver, except this Travis Bickle has a little fetish for forcing woman into doing enemas at gun point. The film is actually based on real crimes committed by an Illinois man dubbed the "Enema Bandit". Anyway he's dead now, so R.I.P you scat-loving motherfucker.
