I was so glad to watch this program as a kid (in syndication) back in the 70s. I've introduced it to my daughter now in the 00s. Almost 50 years and the years haven't aged this program. It's clean and sanitized, but the problems of youth and family are still there.
There's no replacement for Ward Cleaver, who tries to keep his kids walking the straight and narrow, as they find themselves tempted by the likes of Eddie, Lumpy, Larry, Whitey, and all the other kids. I use the problem and solution as teaching tools for my daughter.
Although it can't compete with modern problems, it deals with base issues (communication, empathy) that could create a foundation.
And the comedy helps hide the fact that kids are learning about how to deal with problems.
