Being a huge Stallone and “Rambo” fan, I was thrilled when I first learned that there was a cartoon based on the character. I got hooked on the cartoon and used to watch the few episodes that my dad had recorded for me over and over and over again. So much so that I used to know every dialogue, every musical cue from each of those dozen or so episodes. I’m really happy and grateful to @LiamABC and @Mark M for including “Rambo: The Force of Freedom” in the ROCKS discussion. It gave me an excuse to revisit this childhood favorite. 
I’d first like to start off by talking about the series in general. I think this was probably among the first cartoons to be based on an R-rated movie series. Quite a bold and unconventional move for that time. The only other cartoon that I can think of that was similarly based on an R-rated movie series was “Robocop”. Naturally, I’m sure a lot of the parents’ associations would have gotten a shock when they first learned about this cartoon. But I think the makers did a great job of adapting the movie into a child-friendly show.
The PTSD suffering Vietnam vet from the movie was turned into a righteous and honorable hero who fights for and protects the innocent. It was interesting to note that despite the show featuring a LOT of deadly weapons, not a single person dies in the entire series, which I think was kinda the norm back then. Even though there is a lot of shooting, no one gets hit. Usually the heroes engage in wrestling-like fights where the bad guy is flung out of action. Not that dissimilar to “He-Man and the Masters of the Universe”.
Rambo and Colonel Trautman are based on their movie counterparts, but everyone else is a new creation. Turbo is the grease monkey of the group who creates all the various vehicles and gadgets, very much like Panthro or Man-at-Arms. Kat is the master of disguises and more entrusted with recon and espionage type missions. She’s like the MCU’s Black Widow. I remember reading somewhere that she was based on Co Bao from “Rambo 2”. Obviously she died in the movie so they couldn’t have used the same character. I like the designs of the villains, especially General Warhawk with his silver-tinted glasses and his right and left hand (bumbling) men, Gripper and Havoc. The two are depicted as having a lot of brawns and very little brain and as the series continued they got even more sillier, a fate shared by Bebop and Rocksteady from TMNT. Somehow I always got the feeling that Havoc was maybe slightly inspired by Schwarzenegger who was Stallone’s main rival back then.
There are quite a few familiar and well known voice actors on the show like Alan Oppenheimer, Peter Cullen. Michael Ansara and Frank Welker. I think Neil Ross did a great voice for Rambo. And of course the late James Avery (uncle Phil and voice of Shredder) provided the voice of Turbo. The animation is decent. It does get a bit choppy and out of proportions at times, but that is to be expected from a non-Disney 80s cartoon series.
But the absolutely best thing about the show in my humble opinion is the use of musical cues from the Rambo movies. I think Jerry Goldsmith’s fantastic music is what really elevates the show and ties with firmly with the movie. The moment you hear the music and Rambo “getting ready” for battle (even though he usually is already wearing his bandana and has his lace tied and has his trusty knife, it is still fun to see him do it all over again!
) you know there’s some serious action coming.
Coming to the 5 part pilot, it is filled with a lot of action in various locations and vehicles. There are some nice homages to the movies, like when Rambo hides himself behind a wall of mud etc. The pacing is good and it doesn’t get too crazy or too slow. The characters and their traits are introduced quite satisfactorily as are the vehicles that will be used in the series. All in all I think the first 5 parts set up the series nicely, preparing the audience for a lot more of action and fighting between the Force of Freedom and SAVAGE (cartoon villainous organizations really had the best acronyms!) in future episodes
