Claes and my favorite cartoons are the old X-Men Evolution series, about teenagers with toxic parents in a toxic world who are mutants and have special powers and so save humanity. It is a hopeful story, in these troubled times. This video on Hulu is the conclusion of the entire series, which Claes and I never saw before... he will be very excited I found this.
X-Men Evolution (one of many X-Men productions) is worth watching from beginning to end - series 1-4 - even if you don't have a kid... and all episodes are available free online at Marvel Comics [1], YouTube, and wherever they have licensed their content (there is advertising on each video...).
If they had not made these shows available for free like this, Claes and you and I would never have been able to experience this... now Claes may watch it on my phone... learning to save the world.
See the first X-Men Evolution - Series 1 Episode 1 here [2].
