It's just a kid's show

Yeah, you know this phrase, right? "It's just a kid's show".

There's been so many uses of this phrase that there are just as many people who use it as well as people who hate it with a passion.
Sometimes it even ends up being used AND criticized by the exact same person.

So what's MY opinion on it?
Well, I think both points of views are right, but both have faults too.

On one hand, yes, some shows truly ARE made for kids, and taking it so damn seriously is completely missing the point of the whole thing.
Honestly, would Tiny Toons REALLY be that much better if the characters had lasting injuries and ended up being permanently crippled because of their slapstick?
Would continuity truly help a show like Tom and Jerry? Do they have to explain how Tom and Jerry suddenly became Musketeers and how in the next episode Tom survived being beheaded by the Guillotine?

On the other hand, just beceause something is a cartoon or a show that kids can watch does it mean it SHOULD be devoid of depth or even dark moments.
If Batman the Animated Series lost it's depth and dark moments, that would mean removing the death of Bruce Wayne's parents. It would mean the villains would have been one-note characters for Batman to beat up instead of the deep characters they are now. Hell, in a lot of people's opinions, the villains are the true stars of the show rather than Batman. In fact, I'm one them.
Same with Spectacular Spider-Man. That show had continuity and you could see Peter Parker's growth as a person. Taking that away will make Peter Parker's scenes a waste of time as you simply wait for him to dress up like Spider-Man and beat some villains up with no real context.

Where I think both views are wrong, though, is the fact that there is a difference between a show made for kids and a show made for the whole family.

A lot of people seem to miss this. It's obvious Tiny Toons or Tom and Jerry are totally different shows than Batman the Animated Series or Spectacular Spider-Man. Yet simply because kids can watch all 4, they all end up getting called "Kid's shows".

It's all a matter of demographics.

Kid's shows are shows meant EXCLUSIVELY to kids. Yes, some nostalgic fans or even some casual fans outside of that demographic can still watch it. I mean, I love Tom and Jerry as much as the next guy. But it's obvious that it's targeted towards kids. You're not supposed to think about how things are affecting the characters or what their ulterior motives are. It's just fun to see a cat and mouse try to beat each other at their own games.

Family shows are shows meant for EVERYONE, and that INCLUDES kids. Because of that, while it still won't have stuff like excessive blood and gore or sex or whatever, it still TRIES to speak towards people other than kids. Teenagers could relate to the young characters, adults can appreciate the deep stories and kids can just cheer for the hero or heroine as they save the day or whatever.

It's the family shows where standards should be held high.
Here is where you can complain about continuity errors, characters being out-of-character, writers botching up a storyline, etc.

Kids shows however? Come on, it should be obvious they're not meant to be taken so seriously.
Do you really want to know about the politics of Sesame Street?
Is it really going to help Teletubbies by explaining how those TVs on their bellies work biologically?

My point is, if you ever feel like saying "It's just a kid's show", please make sure the show in question truly IS a kid's show, and not a show for the whole family.
Because as much as I'd love to show my future children Spectacular Spider-Man, it's not going to be until AFTER they've seen their fair share of Looney Tunes.
