Cheadle’s finest hour and proof that Sandler can act. Funny, sad and flawed — like its characters.

Has a good heart, and does some things very well, but may bore passive audiences

Director Mike Binder has twigged on to the fact that if you root Sandler’s genially churlish moron act into a more sober foundation, a vulnerable, believable and even lovable character can begin to emerge.

Emotionally engaging, superbly acted drama with a terrific script and impressive direction from writer-director Mike Binder.

Worth anyone's time.

Successful until the rusty workings of its story gears start to show.

Builds up a nice head of steam...as a warm and quirky comedy of men trying to be men in a post-feminist world...also succumbs to niggling artificialities that drain the story of credibility and genuine heft.

Reign Over Me has some awkward stretches and comedy asides that don’t always work, but the core story is touching ...

Cheadle provides the movie with a sturdy center around which Sandler can orbit with his character's many moods.

To enjoy this movie, you have to look past the small difficulties and inconsistencies (and gender stereotyping) in character and story, soak in the images and the music, and focus on the delicate and interesting friendship between the two main characters.
