Watching Arthur episodes on PBSKids for the first time as a 'grownup on duty'. I like the storytelling and spectrum of characters, but am still ambivalent as for the fitness to the target mindset.
I find that generally the situations are more for lives of 8-10yr olds, yet at that age cartoons may be already too didactic. More younger kids may not face the kinds of challenges depicted. I'm often asked to explain it to the 5yo. Still, the stories are very well written.
My so far most memorable is 'Lost and Found', very relatable almost dream/nightmare-like.
