I personally found this movie to be the weakest in the series. Sure Rambo 3 which is often the most criticized had a fair amount of cheesiness to it, but I still find it a lot more entertaining than the fourth installment.

I'm not saying that Rambo 4 is bad, it's just that I found it to be nothing more than a rehash of the previous movies, mostly Rambo 3.

I find it rather amusing that people call Rambo 4 the best and Rambo 3 the worst AND YET, almost 90% of Rambo 4's basic plot is just the same as Rambo 3:

Rambo is living as a commoner in exile People come to ask rambo for help

Rambo warns them against going into the warzone

The people get caught

Someone comes and informs Rambo about their capture

Rambo goes into the warzone to rescue them

The military leader in the warzone is exceptionally brutal

He is committing genocide

Even the scene where Rambo starts shooting the jeep-mounted machine gun is almost identical to a similar scene from Rambo 3.

The final rescue of the hostages from the POW camp in the rainy night was also pretty similar to the scene in the POW camp in Rambo 2, complete with prostitutes and pigs.

The end where Rambo is walking wearing his green jacket is the same as that from the beginning of Rambo 1, although I am guessing that this was more of a homage.
