Ok...so...I read some other reviews and some are bugging me, while I do agree with others. They bug me the same way youtube comments do, and others bug me because they are just incorrect.
First, I'll address the replacement notions...who cares what replaces what? People grow up and the same show can even still work years later, but also other shows coming around are usually a good thing too.
Next, and seemingly important to say, Debby says in a couple interviews Disney is broadening their horizons and reaching out to more age groups. The humor in this show is very much like "regular" non-Disney sitcoms, but with some Disney extra-silliness thrown in.
Also, the issue that really bugs me people keep saying is the one of racial stereotypes...no...the group is DIVERSE intentionally and Debby helped create diverse characters intentionally to make things mix in humorous and entertaining ways. It also can help the kids learn how to accept one another's differences, possibly creating good moral ideas.
The very minorly edgy and sometimes heading toward sexual or sarcastic humor makes those who normally wouldn't care to watch Disney (like my friend who is also 21) like the show better, and give it a chance in the first place. Debby also has said some jokes are meant for the 12 year olds, then some for the 18 year olds, or 21 year olds or 40 year olds,etc. while others are for the other age groups.
Parents should know their kids well enough to know if they can handle any show or not, regardless of recommended ratings, and this show is funny for multiple age groups like the original sitcoms were (although most were adult centered then too, but not fully inappropriate for kids) and the acting from the kids is very good.
It isn't inappropriate for children, but I wouldn't let really young kids watch it like you might Mickey Mouse Clubhouse or something, because it is entertaining not instructional. It isn't meant to teach and guide, but to occasionally have a moral to the story while causing laughs and shock, like all sitcoms.
Enjoy or not, but nitpicking things when the show is actually not a stupid inappropriate cartoon with too much sarcasm, insulting or violence (yet somehow misconstrued as ok because of it being a cartoon- with generally bad art nowadays i might add) which happens to be on a kid's network is silly and not too helpful. Disney is a family channel, not a kid's network primarily, they just happen to target younger age groups because it's who they can market to, but they want to now move on to targeting everyone in the family for the family network.
