I reckon 'Reign Over Me' could be considered underrated.
It's an Adam Sandler movie which I think puts it at a disadvantage. When people hear 'Adam Sandler' they think of his 90s comedies or the terrible Netflix movies he did recently. But when that man actually acts he is incredible.

Good to see Pleasantville and Dan in Real Life mentioned, both fantastic.
I think Strange Days is underrated. Written by James Cameron, directed by Kathryn Bigelow.
I love it. Didn't do well at the box office though did win a couple of Saturn Awards.
