Lame effort
Rambo was old and stupid in this one. It didn't even feel like a Rambo movie, more a cheap Taken knock off with a violent Skyfall-type ending. The ending sufficed in giving us a suitable amount of killing and gore I guess, but it was a poor, rushed way to get there and there wasn't enough of it through the movie. Rambo didn't seem particularly smart, wasting his bullets on guys clearly dead already. There might have been a reason for why he did that but I'm not sure what it was.
Should have just ended this with the 2008 film, which is a better version of what this film has to offer.
