I liked the fact that it was about realizing life was bigger than your own little world.
It touched on a lot of issues of that time. Nam, Apollo 13, flower children, things such as that.
Also, it covered things that happen in every generation. Schoolhood crushes, the ideals of friendship. Sibling rivalry.
I could identify with a lot of the things Kevin Arnold went through. I remember how it freaked me out to see one of my teachers outside school. It was like they were .... human. I also remember one of my teachers passing away. Too human.
A lot of good things about that show.
