Heavy movies
 

Lookin to make a list of what i think of as "heavy" flicks, the kind that are very well done, artistic, and philosophic but disturbingly difficult to watch because they reveal that which we'd rather keep bottled up. So far all i have really come up with are:

I Stand Alone
Irreversible
Requiem for a Dream
Strange Circus

Others that might approach this genre might include:

Calvaire
Clockwork Orange
Noriko's Dinner Table
Kairo
American History X
The Silence (Tystnaden)

i have yet to see Leaving Las Vegas, but i am guessing it may be a contender as well. Any examples that are glaringly absent??? Thanks.

All the movies of Alejandro Jodorowsky - Santa Sangre, El Topo, The Holy Mountain, Fando y Lis, etc.

Plenty of Lynchian works, Eraserhead leading the pack.

The Elephant Man is another.

Will think of some obscure ones later.

Tetsuo - the iron man
Uzumaki

Driller Killer
Ms.45
Ichi the Killer

Natural Born Killers is one that comes immediately to mind. Bad Lieutenant is another. Thriller: A Cruel Picture also.

Plenty of movies in this list qualify - http://www.horror.com/forum/showthread.php?t=30312

...specially if you list the most realistic ones.

EDIT - Forgot to mention Henry: Portrait of a Serial Killer & Maniac. Two of the finest.

Marat/Sade
Edmund

Salo

Maybe Antichrist and Martyrs, but they're both somewhat of a stretch.

Jacob's Ladder (1990) and Ebola Syndrome (1996 aka: Yi boh lai beng duk) qualify...

Not seen it in years but i can't remember it being 'artistic or philosophic ' - I remember Anthony Wong being a complete sicko though :-)

...oh, it applies all right. ;)
