I'm not sure I agree with this. I'd say that the quality shifted from traditional animation over to computer animation, I would take a handful of Pixar movies over any Disney movie from the past anyday. Besides Beauty and the Beast, maybe a few when Walt was still around, I just can't think of any Disney movies that rival what Pixar/Dreamworks puts out. It's like how TV shows continue to get better, just look at the past 10 years and compare that to older shows.
I'd rather just keep the stuff I watched as a kid in the past, everytime I revisit something from my youth it ends up being aged garbage.
Also you forgot Studio Ghibli stuff, if that's your thing.
You're right, I over simplified. I think I was thinking about big budget movies in general. I think if I were to take my logic, hand drawn talent has to compete with CGI talent which is the dominate form. So hand drawn has a smaller pool of talent and less incentive. But I would say that a lot of stuff I watched as a kid still holds up. Shows like Animaniacs, Batman, X Men, Justice League, Ren and Stimpy, Rug Rats are great. Ninja Turtles, Transformers, GI Joe, and 85% of the other stuff is not....but that's probably with most things in most generations.
Personally, I think hand drawn tends to be better. As far as story telling or artistic merit is concerned I'm not sure the best of Pixar/Dreamworks eclipses old Disney or the best of older hand drawn animation - no doubt that their best are among the best, I just don't think they outright beat them. We may have to save that debate for another time though. That may be a fun debate to have.
As for television being better now, maybe. I don't watch much television. I'd have to think about it, that may be a debate for another time too. No doubt that production value and creative talent are flowing to Television shows at perhaps an unprecedented rate. I'm not too sure how I asses it though. Like I said, I don't watch much TV anymore. I think I can also say that other than Angie Tribeca I don't really like much of the comedy I've seen, but that is a limited perspective and off the cuff remark. Like I said, that may be a debate for another time.
