Looking at my list now, I'd have to take one out and add Bad Timing (1980) to the list. Gun to my head, Flesh and Bone would probably be the one to go, but its still brilliant and needs to be re-discovered. And the more I think about it, Venus in Furs (1969) is slowing clawing its way to becoming my favorite Jess Franco film so it may very well take the place of Eugenie some day.
Raw Deal is indeed an underrated flick. I remember I was actually quite giddy when I first found it because at the time I was equally obsessed with mafia and Arnold movies and here I was getting both in one package. No idea why its still so under the radar, though it being sandwiched in between to huge films like Commando and Predator might have something to do with it.
For shits and giggles and because no country contributed another list, 11-20 might look something like:
Eden and After (Alain Robbe-Grillet, 1970)
Frustration (José Bénazéraf, 1971)
The Brutal Hopelessness of Love (Takashi Ishii, 2007)
White of the Eye (Donald Cammell, 1987)
The 4th Man (Paul Verheoven, 1983)
See You In Hell, My Darling (Nikos Nikolaidis, 1999)
Party Doll a Go-Go! Part 2 (Stephen Sayadian, 1991)
The Exquisite Cadaver (Vicente Aranda, 1969)
Serial Mom (John Waters, 1994)
Dog Walker (John Leslie, 1994)
