I was a fan of Little House on the Prairie with Michael Landon, and despite growing up a Protestant Christian, I don't remember watching a single episode in it's original run.
Stumbled across it on Prime and began with episode one season one.
Every episode has humor, heart, and a good moral lesson without hitting you over the head with it.
My girlfriend and I love it, and would recommend it to anyone. Families in particular
They just don't make shows like this anymore.
