Had watched this at home a while back. It was ok, didn't drag too much while watching it, but can't say it left too much of an impression either.
Wasn't aware that it was loosely inspired by Oil! by Upton Sinclair, a book I'd read in school , and which I think I've almost completely forgotten. Talking of Upton Sinclair, I think it was The Jungle which left quite an impact when I'd read it around the same time as oil. Maybe I'll reread oil sometime..
