"First Blood" is a post-vietnam drama released in 1982, and the first movie of the "Rambo" franchise.
Even though many people believe that "First Blood" is a pro-vietnam action flick, you need to know that this is a false fact. People who say this are most likely talking about the more infamous sequels, both of which are a complete contrast to the original.
If you watch this first installment, you will find a drama about a traumatized man who simply couldn't handle what he experienced in vietnam.
Basically, viewers expecting a right-hand pro-war action movie will get quite the opposite. Yes, there are action-ish scenes as well, but overall, it is a thoughtful and gentle look at a vietnam veteran's attempt to escape his traumatic experiences he had. You can tell that Ted Kotcheff really did everything to make this movie a good one. Also, Sylvester Stallone, though being quiet for most of the movie, gives a terrific performance once he starts talking, proving he IS a good actor, even though being known for mostly playing uninteresting roles. Overall, "First Blood" is a well-made, thoughtful drama and should not be confused with its uninspired, war-fetishizing sequels.
(SPOILERS may follow:)
There are some intense, violent scenes including one bloody corpse that is seen after a helicopter crashed into some rocks. There is a scene involving a graphic injury being stitched up. There are shootouts and spearings.
Rambo slits some officers with a knife. Police dogs are shot, but off-screen.
In a flashback, Rambo is tortured by being slit with a knife (there is some blood). Overall, the violence is not even that strong.
There is one disturbing dialogue between Rambo and a soldier, involving Rambo to tell how Vietnam was and how friends of him died, including VERY detailed discription.
There are 10 uses of the f-word and some milder profanity.
Comparing this movie to other action movies of that period of time, like "The Termiantor" or "Aliens", the violence in "First Blood" is more graphic, more serious. It is not even that action-like, it feels more realistic and can be too much for some.
But since the violence does not dwell on too much detail, older teenagers around 14 will be able to handle it.
