This show will always hold a place in my childhood memories as being one of the best, coolest, funniests, and most violent show i was allowed to watch when i was 8. You have big giant machines, guns, lasers, lightsabers, human hand held guns, martial arts scenes, everything that guys like in high school.
Although you don't have to know the story to enjoy the fight scenes, the story is somewhat immersive, and believable in futuristic sense. Politics play a big part in the show, as do real life problems. Really the only reason anyone watched at the time, was to see giant robots beat each other up, and i think i might go watch one right now.
