Flinch

It opens with a man praying in front of a statue of the Virgin Mary. Joe Doyle is a hitman who lives with his mother, played by the scene stealing Cathy Moriarty. She is extremely proud of his efficiency as a hired killer. Joe kills a man, but is witnessed by the man's personal assistant. THis leads to a completely unbelievable story line with the killer examining his conscience the rest of the film. He keeps the woman in his bedroom with mom insisting that he kill the witness. No need to explain where it all leads, as right up to the ending, it is ridiculous. Don't bother with this stupidity.
