It's rare to find a true gem in the large pile of forgotten 70s films. I'm a 70s film buff so I have dug deep into this pile. Top of the Heap is a hidden gem. Unusual narrative keeps your interest. I would not include this in the "blaxploitation" genre (I have seen at least 30 films in this genre), but the movie certainly explore many themes of being an African-American in 70s America. It's certainly not a top rated movie by any means, but a decent watch and well above average.
