Newfound respect for action genre "Sly is old" - most common comment on "Why wont you watch the movie?". You know what? It does not matter as this is not oiled-skin-muscle-flex at local WWF booth.
The second I have finished watching trailer I knew I will love this movie. It already had this dramatic, sand-in-the-mouth, bloody-nose feeling. These was no dramatic pauses, no over-hyped narration, nothing like that. It was violent. Of course. It's an epilogue of the series that has "Blood" in it's name.
Rambo comes back as a broken man with nightmares about his past. He lives in a hut and is literary waiting for his life to end. There is no joy in his face. He is beaten, washed out. He had few decades to contemplate on his life and it's meaning. And believe me or not - Sly delivers that feeling! Missionaries approach him for an aid. He tries to refuse, but in the end gets convinced by a woman (Julie Benz). This is a point where one can skip or wonder about the reasons.
First of all: Rambo knows what's in Burma. He saw everything war is about. And Burma is the worst. It's genocide civil war. He knows that ideals mean nothing there and worst of all - those missionaries are probably going to die. Rambo does not want to any part in this as it would be kind of his fault too. He is only a human though, so when a woman (symbol of life cycle etc) asks him, he breaks and at least wants to have his conscience clear and agrees to help.
Rambo's instincts were right - missionaries get into the hands of Burmese army. Then the mercenaries are hired for their rescue and Rambo knows he will go into this mission with them.
Notice that during the movie he is referred to by his name John or as "boatman" or whatever. Stallone wants to distance his character from "super soldier" from the man Rambo was in the last two movies. This is Rambo's LAST mission. He does NOT care if he will die or not. He is no longer a hotshot. So no wonder he is not breaking teeth when he gets insulted by the leader of the mercenaries. It does not matter anymore! The rest of the movie is about violence and real(?) war. Rambo fights so ferociously as if his soul was already burning in hell for those 20 years after we last saw him in Afghanistan. As if his desperation, anger, sadness, guilt altogether explode on the screen. It's not pretty, it's not enjoyable and there is no easy way talking about it.
...but I have seen more horrific scenes already. The part in Saving Private Ryan where one soldier is pushing knife into another ones heart and asks to hush.. that one has been haunting me forever. What can be more terrifying than those dying soldiers eyes? "Rambo" is not however a movie that glorifies violence. If it would be so, then the violence would have been more cinematic and plastic and CGI and with a lot more fancy guns and explosions and ... and and. It's shown REAL. So you could NOT possibly enjoy it, because it's a movie with a message.
It's about failed politics, broken ideals and life's cruelty. It's about hypocrisy and silent rage. It's also about hope. Or at least whats left of it when you have seen it all...
