Classic TV Shows they shouldn't or couldn't remake now?

Too many to name. Ironically, many of these shows breathed fresh air onto a whole host of taboo subjects, social, racial and sexual. In today's hyper-sensitized climate, topics and themes that could be treated naturally and sensibly couldn't be touched with a ten-foot-pole now. (And someone will probably put up an outraged post claiming that I just insulted people of Polish descent with that remark .)
