The best show for kids I think that "Arthur" is one of the best shows for kids, and it's one of my favorite shows. I watch it nearly everyday, and I never get bored with it. It's got lessons, and sometimes it doesn't and it's just silly stuff. And I love all of the characters. You can identify with at least one of them, since there are so many different ones. It's just a show about the normal life of an 8 year old. Arthur goes to school, gets homework, has friends, has a family that we can identify with. It's a very friendly and funny show, and older kids can watch it and not feel like it's a "baby show", and younger kids can watch it and simply enjoy the lightness of it.
Overall, it's a great show for anyone who watches it
