I've noticed something regarding long-running animated shows (Spongebob, the Simpsons, Pokemon, etc). As the years go by, the animation gets better, but the quality of the episodes soon become stale by the older audience. A similar event has happened with video games where modern games uses realistic HD graphics, but a lot of people from the internet ranging from Youtube to 4chan complaining about the games not being as good as the ones in the 80's and 90's. This may be just a theory, but I've been wondering if a show will get better if it went back to its older art quality. Has anyone noticed it too?
