The 0.1 score review of this show is so biased and baseless, please disregard it. I have watched both seasons of SD Gundam Force and I'm here to review it properly. Obviously I have my own bias, I enjoy cutesy stuff. This is a family-friendly, kid's anime that is meant to be fun, colorful and upbeat. For a comparison, this is the Transformers: Rescue Bots of the Gundam series. (Another series I greatly enjoyed, if you liked that, you'll like this.)
If you like cute anime, fun characters and silliness, you will enjoy SD Gundam Force. It has an overarching plot that revolves around defeating the forces of evil through the bonds of love and friendship, but it also often takes breaks from the 'heroes vs villains' story to do things like: fight over who gets to go the cake factory, make 1000 rice balls for a guest, or just relax and look at clouds. The cast of characters is basic, you've got a reliable leader, a hothead, and an elegant ego... plus an enthusiastic kid to cheer them on and glue them together... sometimes *literally*.
It also actually gets fairly deep at times, going in depth into the motivations and emotions of not just the heroes, but also the villain characters. You will see not just *that* they are evil, but oftentimes *why*, and that the difference between heroes and villains is just the decisions they make, because all people and Gundams have souls. You may end up sympathizing with quite a few of the misguided souls of the show.
The first and second episodes when watched together will really give you a sense of what you're getting into. This is a story about children and bonds, about meeting a new friend and discovering a world outside of the ordinary. I would say, if you want to make a decision, watch those. Also, the soundtrack for this show is incredible, another way I know the previous reviewer didn't actually watch the anime! Feel free to look up the themes of the three main characters on YouTube, especially the theme of Zero, The Winged Knight. It's a beautiful track.
All in all, this is a show for a specific audience! If you're in that audience, you will enjoy it. If you aren't, it won't work for you. But that other review was just so godawful and uninformed, I was moved to attempt some form of justice.
