Recommend me movies like The dead poets society.

DPS + Saving Private Ryan = does not compute.

Master & Commander - The Far Side of the World, also by Weir, is in my opinion thematically close to DPS, but grittier. Excellent movie.

Magnolia (1999) is a fantastic and touching film, I'd highly recommend it.

It's not really like DPS, but I love both movies

I won't be able to reply for most of the next comments. But I'll surely read then all.
So thanks in advance :)
