Man Bites Dog (1992)

[cranefly]

Yeah, I watched this earlier in the year. It was a funny black comedy, at least for the first two-thirds -- which is why I didn't put it among my most depressing. But the final third seemed to cast off the black comedy. The serial killer lost his charisma and turned into a drunken mean bastard.

It got a bit unpleasant to watch -- not quite a total downer, but close.
