That's something a lot of us have agreed on as one of the show's weaknesses in recent years; that and the overabundant use of celebrity guests to the point that they turned Word of the Day into a daily celebrity showcase, and almost every street scene having a celebrity guest star -- it was just a bit much.
While I don't like the "kids don't know who celebrities or what we're parodying" logic, I'm glad they've toned it down. That and the fairy tale characters since the 90's. They've been
waaaaay overdoing it and I get the feeling why they're doing it and I just don't like it. It's somehow to keep the characters as pure role models, so they pass all the drama and conflict onto hyperactive versions of fairy tale characters. Plus there's also that "you know the story and we can use that to teach you" thing which seems either a brilliant turn or lazy. Baby Bear did start out as one of those but became his own thing, mainly due to Rudman needing a character of his own. I'm very mixed about the fantasy angle. They always had some level of fairy tale and magic elements, but they were tempered with Looney Tunes style gags and encroachment of reality humor. It's been more cartoony since the 90's and the ATC era, but they push it too far recently. And I can't even blame that on the creation of Abby. That was a long time coming and would happen with or without that character.
See how much more believable and real that looks compared to CGI?
I'm ambivalent about CGI backdrops. It surely seems like something Jim would experiment with at some point. I think it works specifically for the segments that use them, where they would spend a minor fortune and have to constantly reuse backdrops otherwise. I mean, they purposely made an episode where Telly has to babysit a duck to reuse the Telly Duck puppet from the Peter and the Wolf special, they used that
ugly Mouse Zoe puppet from Abby in Wonderland for a season. They're going to reuse the heck out of anything that costs that much time and money. The segments they use those CGI drops for are the fantasy based segments like ETM and Crumby Pictures where they'd need to constantly change settings. I get that. I'd love to see a fixed series of sketches that use a practical backdrop over and over to make it worth their money, but with segments that have ever changing scenery, of course they'll go for the cheaper alternative.
But it does make it look a little cartoony, I agree.
