DC animations are fine, adequate cartoons, but they never excelled at anything except perhaps the occasional voice acting, but they are decent. Legion of Super-Heroes is NOT OK.
The lead character is Superman's female cousin who, as a spoiled and entitled teenager two months on Earth, cannot adapt to the primitive ways of the 21th century. So Superman uses a gimmick to send her to the 31th century, to train in a hero academy. Wait, what? Don't think about it, just go with it. In this academy there are only other teenagers, all speaking and acting exactly like teens today. After 1000 years of history!! Don't think about it, just go with it. The villain, then, is a shadow organization that exists in both timelines, known to no one, but exposes itself completely for the sake of the plot. Then there is some side-plot about acceptance regardless of relatives or origin and a ridiculous ending.
That's it. Everything is telegraphed tens of minutes ahead and that's saying something for a 80 minute film. There is nothing special in this thing except for how bad the story is. It's as bland as a corporate hallway. So if you want to spend the time to watch a completely forgettable hero in a made-up inconsequential pocket world that has nothing to do with the characters and universe you know from other DC stories, go ahead.
