I think he fact that you're a kid when you watched a lot of cartoons does have a big impact on how positively you viewed it. But it does seem to me like the general quality of cartoons has gone downhill. There are still plenty of great shows, like Spongebob, Adventure Time, Phineas and Ferb, Regular Show, etc .. but .. I don't know .. I'm also a big fan of actual hand drawn cartoons (and anime), so a lot of this new stuff that is all digital just doesn't feel right to me.
There also seems to be some decent live action stuff out there (I admit I've watched and enjoyed some Wizards of Wavery Place, as well as whatever else my nieces like to watch), but really -- does anyone else remember TGIF on ABC? Freakin' a. Family Matters, Step by Step, Hangin' With Mr. Cooper, Boy Meets World, Sister Sister .. Can anyone compete with that?! HM??!!?!?
P.S. Tia and Tamara are total babes, even to this day! I remember watching some made for TV movie they did called "Twitches", which was more or less a Harry Potter knockoff and .. I probably wouldn't have watched it if they weren't in it. Or at the very least, there would have been a marked lack of fanboy squees.
