I have a 4 year old daughter and a 3 year old son. When we got the Hub for free for one month, I DVR’d all the My Little Pony and Strawberry Shortcake episodes for my kids plus Transformers Prime and GI*JOE Renegades for myself. That just about ate up all my DVR space.
For a modern kid’s show, I do find My Little Pony: Friendship is Magic to be entertaining. But I don’t think it is even close to an “adult” cartoon like the Simpsons, Ren & Stimpy, etc. It’s one of the few current cartoons where most episodes revolve around a plot to teach children values, similar to the Filmation MOTU cartoon.
