Well this isn't a company but I admired that Lazy Town show for encouraging exercise and activeness. Plus it could be very funny and not just preachy.
Lazy Town looked like a Nightmare Version of a European Kid's show... I really think it did. I could almost picture it as part of a Tim Burton movie.... actually, anyone ever see the movie "Spy Kids?" It reminded me of that show the villain had.
But I have to say Dora and Blue's Clues are what's wrong with kid's educational television. They are unenjoyable by anyone over the age of 5, they don't have any snide humor or anything that challenges kids, or gets stuck in their memory for years, making them one day say "OH! NOW I get it!" And that's the best thing you can do for a kid's show. SS, even the Elmo-centric 2 year old focused version of itself manages to make snarky little asides... Grover playing with a Marionette and saying "It must be fun to be a puppet" or the Preschool Musical skit. That wasn't a parody, that was Disney getting Pwned!
Shows like Curious George and Arthur (which basically is like the Simpsons for young kids to me) have that sort of wit about them, and that's what makes Dora great. Dora is essentially a computer game that's on television, and you're watching someone else play it.
And I feel making an older version of her makes about as much sense as making a cartoon called "Adventures of War and Peace: Sharing and Caring in Russia." You're trying to get an audience that doesn't like or even care about the project. If they make money off of it, fine... I just don't think this will.
On that subject I do not see how this is like Rugrats, All Growed up. I mean, sure, that series was inadvisable, but they had a nice "What if?" situation (that frankly worked better as a special). You saw the characters' personality manifest as older kids with a working understanding of the world (something they didn't have before). Of course, it was during Nick's tween toon phase, where they also had Rocket Power (the one and only Nicktoon I'd admit to truely hating) and As Told by Ginger... so basically, you got the same show with different characters... plus, the appeal of Rugrats was when they were kids, exploring the mundane world of the adults, especially when the audience gets to see the interactions between the adults. Remember, Tommy and Angelica thought the Grand Canyon was a wall of tires in a garage.
