As stated, it was an incredibly profitable movie, which means there's more profit to be made.
The Rambo series is certainly fascinating in its evolution. The first one is just as much a potent tragedy about the hell soldiers went through in Vietnam and how their country let them down when they returned as it is a thrilling action movie. The ending itself is basically the antithesis of the action movie; how many action movies do you know where the hero breaks down in tears and gives himself up to the police? That's why the movie's held up decades after it came out.
That scene really gets me good, and I agree that the way the movie is changed to make him more sympathetic is why the ending works as well as it does, I first saw the movie as like a teen, staying up late one night watching TV, and I was really taken by the film, the reputation of the other ones had given me the expectation that it would be more of a dumber action movie, but I found it so thrilling and engaging.
When he breaks down into tears at the end, I was in awe, I had never seen such an emotionally gripping scene of a man before. This was something had never even occurred to me as a lad, the strong and determined action hero falling apart and just bawling like that.
It was surprisingly popular, relatively cheap to make, and made a shitload of money. In Hollywood that means sequels. See also: Friday the 13th.
Gee, there's a movie which made stupid amounts of money. What were they working with, just about $1 Mil? Then they made something like x50 that on domestic box office sales alone, I think it must have been near x100 in worldwide revenue, it's fucking nuts how profitable that movie was, and it makes me slightly light headed every time I think about it,
particularly because I think it's only just kind of ok.
usually not a fan of an adaption changing the tone too much, but sometimes if they do it can be great. least it gave us this:
I think that you can make something very good with an adaption when changing a lot, such as with Jaws, or Starship Troopers, a sheer
disrespect for the source material you're working with does not have to be negative or poisonous in all cases.
