Potentially John Rambo could have had more punch than the boxer movie Rocky Balboa, but it’s a dud. At least with Rocky you had some nostalgia albeit forcefully jammed down the movie goer’s throats with some old clips and locations.
This movie is emotionally dead. Such a big waste of opportunity if you think about it considering its intent was, like Rambo III, to try to bring attention to a war torn country: Burma in this case. But when part III succeeded, part IV failed.
