What's the most active surround track in a non-action film?

[Bluyoda]

Action films, including fantasy and sci-fi have great discrete surround activity much of the time, but dramas/comedies/romances etc. not so much.

Which non-action film has the most active discrete surround track?

Animation doesn't really count.

EDIT:

What I am looking for are films, such as Days of Heaven, Immortal Beloved, or Doctor Zhivago, where action clearly isn't of any major importance.

Titanic has too much action to qualify IMO, as it is a disaster movie, and those usually contain a fair amount of extras.

As I wrote above: Dramas/Comedies, and not action comedies. ETC.
