^Of course the show is for kids, but the point is, that doesn't have anything to do with the quality of the designs. Frankly I'm appalled by the attitude some people in our culture have that "for children" automatically equates to "low-quality." Surely we owe it to our children to give them the best effort we're capable of in everything we do for them.
Not to mention that anything made "for kids" should be watched by their parents along with them, so it's only good sense to make it appealing to adults as well. Not to mention that adults are creating it and have the right to make it an enjoyable creative experience for themselves. There are countless things made "for kids" that have considerable adult appeal as well -- including many earlier seasons of Super Sentai
and Power Rangers
. So if your intent is to use "it's for kids" as an excuse for low standards of quality, you couldn't be more profoundly off-base.
