Films that are so unhinged you're not sure whether they are disasters or masterpieces (or both)

Putney Swope!
Bamboozled is confirmed shit but it has the seeds of like 20 masterpieces, maddening.

I agree stuff like Fear and Loathing are pretty cut and dry. I used to think Natural Born Killers was on the cusp of this 'genre'; I watched it once and thought it was just a broad tacky temper tantrum of a film. The 2nd time I thought the same thing except I liked it instead of disliked it. Nothing much to figure out though.
