Steven Soderbergh's Che (Part One) will be airing this month on the Sundance Channel. Also, if you have Time Warner Cable, you can watch the film in its entirety (Part One & Two) for free via On Demand.
I know the film received mostly horrible reviews (or was just blatantly ignored) but I absolutely loved everything about it. It's one awesomely long documentary-style character study of the ultimate revolutionary. I got to see it, in full with a brief intermission, in theaters with my mom who turned me on to Che Guevara. It was one of the best movie-going experiences of our lives. Even if you don't like Che's politics, it's worth seeing for the fantastic editing (no I'm not being sarcastic), cinematography, and acting. Benicio Del Toro IS Che. He was robbed of the Oscar (and Sean Penn agrees, surprise surprise) but he did win at the Cannes Film Festival.
Basically, I highly recommend you watch it.
