Read this. The translation of Rambo: First Blood Part II.
It's not good. Probably the original ain't that swell either, but the translation is kinda lame, and there are a couple of places where I knew what had to be the original and the translator did not know how to put it into Hungarian. Those points are a bit cringey.
The novel First Blood started the Rambo saga, by adapting it into a movie, then they made sequels to the film. The second movie was Rambo: First Blood Part II, and this novel is the adaptation of that, and not the other way around. Most likely this fact also reduced the quality.
