I'd second Big Hero Six.

Most super powered stories are not very equal at all. My favorite, the Parahumanverse, is blatantly unfair. Almost all of them have at least some degree of "these people get powers for reasons outside of their actions". Even if it's not everyone, it's definitely some.

Basically, if you posit some sort of amazing super-tech, you gotta justify why only some people have it. Otherwise, it's not a superhero tale, it's just sci-fi.

Marvel's probably the fairest outta the well known ones.
