Seriously good serious films

I don't think this thread as been done before so here goes. i have fairly large dvd collection (about 300 or so now ) and have fairly varied tastes but tend to enjoy serious , well acted , thought provoking films the most so here is my top 10 ( i could probably list about 30 )

1. 1 - Schindlers List
2. 2 - The Constant Gardener
3. 3 - Saving Private Ryan
4. 4 - Syriana
5. 5 - 21 Grams
6. 6 - American History X
7. 7 - Narc
8. 8 - The Life Of David Gale
9. 9 - Traffic
10. 10 - Munich

what... no pulp fiction??

QT's films are fantastic with good serious plot lines although a lot of the dialogue has slightly comedic edge to it which in my opinion simply adds to the enjoyment, i was thinking ultra serious for this particular thread as Pulp Fiction would be in my all time top 10
