I remember watching this as a young teen when it first came out in '74. The first few seasons were the best.The writing and humor in the first year was subtle, but funny. The attitude was sentimental, but sweet. By the end it was redundant and mediocre I think it would have been better if it had ended after 4 or 5 seasons, I mean , I thought Fonzie was funny, and Winkler is a wonderful actor/director, but when Fonzie, Chachi and Joanie became the focus of the show, it lost quality and perspective. By the end of series, it was supposed to be set in the early to mid 60's,but the fashion and attitude were pure 1970s/80s. The hair on the men was too way long and the women (aside from Marion) were dressed too modern. LIke M*A*S*H and The Waltons, it wore out its welcome when it outgrew its original premise.
