Rambo II is a love hate movie. Some hate people it and some people love it. I'm part of the latter and personally consider it one of my top 10 best action movies.
Rambo: First Blood Part II starts a little after First Blood ends where John Rambo is incarcerated to hard labor were Col. Trautman comes to offer Rambo a mission to gain a pardon and help close a door of his past.
Rambo returns to Vietnam to scout out a former POW camp to capture photos of POWs that Rambo's superiors don't believe exist. Little does Rambo and his superiors the camp isn't empty but full of long forgotten United States soldiers and Rambo goes all out to save them.
Casting is actually quite good even with Stallone's acting. All the actors fit well to their characters and all of them are believable even with Rambo's larger than life persona.
Visual FX are excellent as the movie is pre-CGI everything that is now a days and so the explosions and fire effects are very believable.
Soundtrack is instrumental and only has one 80's song at the end which is one of the only bad part of the movie.
I know some think it's cheesy 80's over the top action movie but I enjoy it immensely and consider it the epitome of the 80's action movie.
