The two stars...[Casey Affleck and Matt Damon]...both playing characters named Gerry, wander across the desert for some reason, and if you enjoy watching them on any pretext, you'll probably enjoy this; if you don't, you won't.

Absolutely transfixing at one moment and unbearably boring the next.

The picture can be read as a warning about the perils of improvisation -- a neat joke given how fruitful that method proves here.

What makes Gerry worth watching is in how it perfectly captures what it’s like to get lost in the wilderness.
