According to Wikipedia The Honeymoon Killers is Francois Truffaut's "favorite American film." Wikipedia cites a 1992 New York Times piece, which pops off the quote without any solid attribution. Pat digs deeper and discovers the truth for this week's episode, though you probably could have guessed that Wikipedia isn't quite on the level.
Anyway, Leonard Kastle's 1970 ultra-low-budget true crime film is one of those where we spend a good chunk of time wondering just why it's in the collection anyway. The answer may solely be that a young Martin Scorsese was originally hired to direct, shot at least one scene, then was fired for taking too much time. The end product comes off as shades of John Waters without being purposeful or self-aware. So bad it's bad, and unhelped by its shocking use of violence.
