Y'know, it's not just puppets, adn it's not just animation, there's plenty of advances in technology that many people aren't too fond of: music is perhaps one of the biggest ones there is - I've noticed a lot of people (particularly older people) say the same thing about music having losts its "warmth" since we've gone with digital technology, from CDs to MP3s and digital albums - they say the "warmth" of the music came from the static and bumps and scratches you heard coming from the record player. Heck, some people out there say the "warmth" of home video is lost on DVD and Blu-ray, with some saying they miss that fuzz and noise that came with VHS (that I can certainly live without). There's an interview with John R. Dilworth (the creator of COURAGE THE COWARDLY DOG, and the artist behind those NOODLES & NEDD shorts on SST) on YouTube where he and the interviewer both expressed how much they miss the days of where sound effects in cartoons were recorded in airport hangers, giving an obvious echo and distortion to the sound.
