There were plenty of good shows [[subjectively speaking). With that said, the 70s were pretty brutal for shows that followed formulas. SWAT, Baretta, Starsky and Hutch, The Rookies, and tons of other cop shows were pretty similar. Archie Bunker and M.A.S.H. changed sitcoms for the better, but most of them pretty much sucked. Sanford and Son easily stands out as an exception early in the decade.
