Can't call this "Worst Movie Ever" --- Not a movie
If you don't like a headache, take aspirin. If you're the type who actively seeks headaches, lay eyes upon Hardcore Henry. I say "lay eyes upon" because you can't actually "watch" this as you would a movie. Sure, you might say that you can "watch" a GoPro commercial but I would call that interfacing with a product. This experience was like interfacing with steaming poop.
