Well, this list is far from exhaustive, and those are all great shouts. Paths of Glory is another favourite, and if I had to pick a Hitchcock film for this list, I'd probably go with Vertigo. Schindler's List is another that I almost included. And I agree with you about Conrad Hall. Road to Perdition looks magnificent.

I'm not sure I agree re: Barry Lyndon and Hero being too beautiful in the sense that the narrative is lost. Hero is a coded celebration of the collective greater good over the needs of the individual (very in keeping with Chinese communist ideology). As for Barry Lyndon, I think the theme of the film is best summed up by the title card at the end, which states something to the effect of whatever the social status of those who lived and died in this story, they are all equal now (I am not sure if this was derived from the Thackeray source text, as I've not read it).

Whilst Barry thinks he acts with noble intent, he often doesn't, and lacks the self-awareness to realise his folly (particularly his brutal treatment of Bullingdon). As with all his films, Kubrick's unsparing eye depicts his protagonist in all his flawed humanity, honestly but without judgement. He shows Barry's aspiration to wealth for the emptiness that it is. Hence the final text about the characters all being equal in the end.

Anyway, as I said, some great extra shouts. :)
