***No spoilers follow***
Sure there are a few things that don't quite follow, but if you are a fan of the old Hitchcock and Twilight Zone episodes, you will appreciate this suspenseful puzzler of a movie. Centered around a psychiatrist, his depressed patient, and a fictional medication, things devolve into a murder which we witness. From there, we are never quite sure what is true and what is not. Entertaining, suspenseful, and sure, a few loose ends but who's counting? A fun way to spend an evening, and after the show, you can explain the twists to our companion!
