We here at Complex Pop Culture truly believe that movies can be enjoyed on a spectrum—from the truly spectacular to the truly terrible—there's usually at least SOMETHING quality, even in the worst, worst films. People don't enjoy The Room just because. But if anything can ruin a movie, no matter the quality, it can be the ending.
It's like the Olympics, if you don't stick the landing, then the whole thing is pretty fucked. So see if you agree with us about these very good movies (including many from a certain director...) that completely bomb the landing.
