I kind of thought it would be a mindless action film where Sly goes around killing the bad guys in the jungle with his machine gun and that's about it. Like Predator, I guess, just without the Predator.

I was wrong. It's excellent. I found it very entertaining, and also quite sad. Sure, Rambo is this bad-ass, super elite soldier who can kill a man practically by looking at him, but I never realised there was a subtext quite so…
