The "For Kids" portion of the entertainment industry has a few flaws. I mostly attribute this to the attitude that "Kids are dumb and won't care what crap we subject them to." I mean, just because children are immature and not as experienced as us, does this mean that they won't understand "Batman wants to make the criminals drop their guns so he's going to throw a baterang at them" unless we spell it out for them?
Generally, the priority for kids media goes like this:
1. It's acceptable for kids to read (No sexual themes, excessive violence, language, etc.)
2. It's educational in any way or form, even if only a fraction of it barely teaches children anything at all.
3. (Optional) It rhymes or has funny made up words.
4. (Optional) It has colourful and memorable characters.
5. (Optional) There are actual words or dialogue.
6. (Optional) There's something that kids will find "cool" like robots or the Internet.
7. (Oh yeah, completely optional and unimportant) IT DOESN'T SUCK.

Sadly, it becomes very evident which of these were accomplished when you look at the covers of books such as this:
