The Pitch: 20 years following the events of Rambo III, John Rambo once again picks up a huge gun and this time tackles the political crisis in Burma. Colonel Trautman is nowhere to be seen (actor Richard Crenna passed away in 2003), and Stallone is now a whopping 60 years old (as well as, for the first time in the series, taking up directorial duties himself). The Result: Though some might argue that the Rambo series benefited from a break given that the only particularly decent one out of the first three was the original, a major issue with 2008's Rambo is that, due to Stallone's age, he's confined to standing behind a giant artillery gun for the final set-piece rather than actually moving around much. Given the movie's gritty nature, it would seem patently ridiculous if stunt doubles were used to make Rambo fly around and run like a man half his age, yet this just makes us think the movie should have been made at least a decade earlier. The lack of a Trautman cameo is also a shame given how much he meant to the series, and though the movie delivers a gratuitously, almost hilariously violent finale, it still felt like too little, too late. It's still the best of the Rambo sequels by far, and was a financial success, but it was the lowest-grossing movie of the franchise, which when considering almost three decades of inflation since First Blood, is rather embarrassing.
