Classic or Dud: Miles Davis "On the Corner"

I feel like this is absolutely classic. Funkiest thing ever on record, precuror of trance (for better or worse), way ahead of its time. Dudes couldn't even hear it for years after it was released.

But I know quite a few people who think its Miles' worst album, that its just amelodic noisefunk, that Miles ruined jazz forever, etc.

Thoughts?
