Jedidiah Ayres blogs about so many underrepresented crime shows, movies and books at his blog. 

Right now he is in the middle of listing his favorite 300 crime-related movies of the past decade.  Many of his choices are obscure or foreign flicks. 

I just watched a movie out of France called LA French (The Connection), which was excellent.  It was a combination of Heat, Goodfellas and The French Connection (it is based on the heroin smuggling of the 70s). 

Many of these are on Hulu, Netflix or Amazon Prime.
