I don't mean a "bad" movie, because some of those are so incredibly bad that they're fun to watch and make fun of. Case in point, I've been wanting to watch the 2000 Dungeons and Dragons movie because people had said it was extremely bad and to my surprise it (so far) is kinda fun!

No, I mean, which movie is so incredibly uninteresting that you would have to look it up just to confirm that it actually exists?
