The film is pretty damn awful, especially when compared to Part 4.
The background music is over the top, to the point of being annoying. He mumbles his way through it, and for the vast majority of the film very little happens.
This is a shame because it's not the send off he deserves.
If you want to remember the Rambo films as being decent, don't bother watching this one at all, because it's a real let down.
