Hi, I'm a member of this board and I don't post here often, but I have a question that I've been wanting/meaning to ask for the longest now. I read the mention of some cartoons still holding up and having aged well while others haven't. That and this question has been bugging me for a while now: How does/would one know this for sure??? Because I can't see it. Are there some certain kinds of signs? What does one mean by that? How can one tell? What is it about them that makes them fall into one group, and some in the other? I just don't get that. Like at one time, when those who were little watched certain shows that used to be/seemed to be great suddenly aren't so anymore once the viewer grows up and has second thoughts looking back on that. Why is that and how does one know what makes for the perfect series that are still enjoyable? Thanks.
