I'm probably late to the party on this one, but if you haven't watched OJ: Made In America yet, do so. Seriously, best TV I've seen in a long time.
It's 5 episodes and around 8 hours but very worth it. I think it's still on SBS on Demand.
Bizarre, thoughtful, brutal, ironic, crazy and epic. Covers his entire life, not just the murders and trial. Puts everything in historical context, and you'll find your sympathies and opinions veering all over the place.
Does contain very explicit crime scene pictures though, so be aware of that...
