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

Ramar Of The Jungle, Captain Gallant Of The Foreign Legion, The Life & Legend Of Wyatt Earp, Father Knows Best and such, by today's standards, "dated" fare as Peter Gunn, 77 Sunset Strip and Hawaiian Eye. Some shows, like Gunn and the similarly "ambianced" Mr. Lucky are of their time and of their place, and there's no bringing back that that compelling Noir world of gamblers, petty criminals, jazz musicians, beatnicks and con men. The waterfront dives (all million dollar condos now), with the foghorns in the background just wouldn't fit into a 21st century show. Even done as period pieces, meticulously detailed, they could be made to look handsome, but their emphasis on offbeat characters, the lack of much action, would likely not attract many viewers under fifty.
