Todd Russell’s review published on Letterboxd:
The movie opens with a more mellow rancher John Rambo, herding horses, playing uncle to a young woman, and building tunnels under the house property where he calls home. It doesn't take long for trouble to find Rambo and we all know what that means.
I enjoyed the setup time and extra background on Rambo's character, but will admit some may wish the action would start sooner. The film is shorter, maybe a bit too short on the back end. Explaining what he's been up, how he is living in current day. I wish the antagonists in the story were treated to even a tiny bit of backstory. They just seem like cardboard bad guys that could have been dropped in just about any vengeance storyline. The lack of depth makes most scenes with them less dramatic.
Caught our first ever 4DX showing and the first time this showed in Las Vegas in 4DX. We both thought the 4DX enhancement added to the experience.
Wife and I both enjoyed this move, especially in 4DX. I'd rank this somewhere between First Blood and Rambo II. Definitely better than Rambo III and the last one in 2008. It was refreshing seeing a new background and backstory vs. killing random bad guys in some foreign destination. Recommended.
