A few warning signals here: (1) Tim Robbins in (2) a film dealing with soldiers returning from Iraq which (3) went nearly directly to DVD. I was expecting something earnest and tediously left-wing. But such are the benefits of low expectations: it wasn't good, but it wasn't awful.
Robbins plays grizzled vet Fred Cheaver, ending his military career, returning home after being injured in Iraq by a falling porta-potty. He makes the acquaintance of TK (Michael Peña) and Colee (Rachel McAdams), on leave to recover from their much less amusing injuries. Circumstances cause the trio to start off on a cross-country road trip in a rented red minivan. Many incidents ensue, colorful characters are encountered, lessons are learned.
The movie treats its main military characters with respect, and all three are fine actors. Most civilians they encounter treat them wonderfully; a few exceptions are clear bad apples.
The main problem is that the movie never quite lifts off from its "Little Miss Sunshine except with soldiers" premise. The writer/director, Neil Burger, previously wrote/directed The Illusionist which was much, much better.
