Sicko by Michael Moore
Moore, above center, did his damnedest to end gun violence (Bowling for Columbine) and the Iraq war (Fahrenheit 9/11). Now the U.S.'s top docu-comic goes after the health-care industry, traveling to Britain, France and Cuba in search of better care. The film is angry, instructive and so funny you may pop a stitch watching it.
