Here's an example of shows that don't hold up (which fits as I go into detail why)
You guys ever hear of the Superhero Squad show?
If not, than you should know that this show is terrible. The characters are annoying and are limited to one character trait (I.E Hulk is the stupid one, Iron man thinks technology solves everything, ect) the humor is only funny if you find lazy fart jokes funny, and the animation is very cheap, making look more like an anime abridged parody than a show fit to air on television.
I am ashamed this show was my introduction to great Marvel characters such as Flacon, Modok, Thanos, Adam Warlock, Ms Marvel (Carol Danvers) Scarlet Witch, the skrulls, Dr. Strange and so many more.
