Having just seen this yesterday, it is a brilliant Documentary following the development of Indie game Designers... Super Meat Boy, Braid, Fez and other current classics that are in the hall of fame among gamers.

if you love Indie Games, you will love this movie! :D

Note: Pay special attention to one of the programmers comments about game launch times/delays aswell as his comparison to Valve. :) I chuckled.
