Watched First Blood for the first time tonight (saw Rambo: First Blood Part II and Rambo III years ago). It's pretty awesome. It's totally weird to see the character morph into a crazed, post-traumatic Vietnam vet gone postal to grizzled vet dropped into his element and let loose to ONE MAN ARMY to washed up, cynical war vet with nothing to live for.
Oh, and the first two and the last one are awesome. Rambo III kind of sucks.
