As a parent of two small boys, Teen Titans Go is probably my favorite thing to watch with them. I'm not sure if Lucario's gripes are because it's not story driven like the early 2000's version was, or the zany nature of the current show doesn't jive with a lot of DC's other properties, but most of the episodes I've seen have been fun, silly stories. There have even been a few episodes I've seen that have made a point to be self-deprecating, such as one where they make a point to be "super serious", changing their animation style to look all bulky and brooding while fighting crime, and one which covers the topic of cartoon violence, and the characters playing in different animation styles to match loony-tunes, and old anime to gauge what makes violence "acceptable".
If you're looking for a short, silly cartoon with a superhero premise, can't do much better than this show. Reminds me of old Powerpuff Girls episodes in the good ways.
