User blog comment:Creeper50/What's the worst movie ever?/@comment-4715955-20160308021230

I don't think deliberately bad movies like Sharknado should really count, any more than deliberately bad fanfics should be on a "worst of all time" list, because they're all made for lulz by people who know they're doing everything wrong. Forgiving the fact that, whether you crap your pants intentionally or not, you still crapped your pants.

The "worst films of all time" should be the ones that are bad because they're soul-crushingly boring -- the kind you can't enjoy ironically, they're that bad. Monster A-Go-Go, The Beast of Yucca Flats, Manos: Hands of Fate, Gerry would all qualify. Ask the MST3K guys how much fun they had watching some of those movies.
