I get to see a lot of children’s cartoons. Zach Weinersmith is completely right on this one.
In fact, a few years ago, I tried to rewatch my favorite cartoon as a child, Voltron, with the idea that I might show it to my own children. Let’s just say, my children still have not seen that iteration of Voltron. My imagination is still pretty childlike*, but this was too much to ask**.
*I can provide references.
**As much as it saddens me to say it, this is also true for Airwolf.
The Finch and Pea 
Inspector Gadget withstands the test of time though. I still found it funny when rewatching it as a “grown-up”.
I have an attitude of not revisiting many childhood things I loved. “Die Hard” holds up well, I think. Not sure what else would. I’m mildly optimistic about the upcoming Star Wars: The Force Awakens. Going back to watch Voltron would be horrific, I imagine; though as a concept, Voltron is still awesome (I loved the Robot Chicken episode where they had Voltron get involved in a dance competition.
