As with any form of literature, or in this case, its animated counterpart, you can only objectify them so much. While I'll agree with the points you made for determining quality, individuals interpretations of these points may differ. And besides, if people enjoy it, I don't see how it affects you personally that the quality isn't top-notch. If you don't want to watch it, then don't. None of us here who enjoy it are trying to force any of you who don't enjoy it to do so, whilst you guys are trying to purposefully ruin our enjoyment of something just because you do not personally enjoy it.
