If you go into Rambo just for a good time and don’t want to knit pick stuff, I think it’s enjoyable. Pretty much same thing as the Fast and Furious movies. Not good movies, but if you turn your brain off and just go in for a good time I think you’ll be satisfied.
I thought Rambo was a good action flick. Gory as hell. But it doesn't feel like a Rambo film. He didn't look, talk, or act like Rambo. 7.5/10 for me.
