36 Quai des Orfevres
I have just watched 36 Quai des Orfevres and was very impressed. It is better than Heat because it is more realistic. Whilst the movie is bleak in many ways, the underlying (albeit ambiguous) integrity of the main character is never in doubt. He is a good cop in a very dark world. Unlike Heat the main protagonists are both cops and the criminals are never shown in any positive light. Compared to Vrinks, Klein is evil, yet they both commit criminal acts for what they see as the greater good.
Embedded in the good is a bit of the dark.
