I've seen far too many awful movies in my life and it seems that many of them were made by either the Troma Team or The Asylum so we'll skip all of those (like Toxic Avenger or Sharknado where you pretty much know what you're in for from the beginning). If you're in the right mood, Plan 9 From Outer Space is actually quite funny, and Cats is visually interesting (at least), and Howard The Duck is crazy in a way that could only have happened in the 80s, and I can't be too hard on The Happening because Zooey Deschanel. I can even put up with The Psychotronic Man despite it being a movie so awful it doesn't ever get listed as a bad movie, it just gets entirely forgotten like a deeply suppressed trauma. But you know what movie I would rate as the absolute worst one I've ever wasted any of my life on? Attack Force. I really don't get the appeal of Steven Seagal, and I think Attack Force really plumbed the depths of his inability to act convincingly. I would willingly watch the deplorably bad "Class of Nuke 'Em High 2: Subhumanoid Meltdown" before anything with Seagal in it again.

It was a movie called "Fearless Frank". Was on TV in 1978, on a Saturday morning. I turned it on for something to do before going to work, and wound up watching the whole thing, because I couldn't believe this movie was that bad; it HAD to get better. It didn't.
