Yea, PM is a great program. SS is ok, I like it, but it's not a heavyweight OTR program...
I'm not always against irreverence and breeziness. Vincent Price is very likeable as the Saint. But Dick Powell's Richard Diamond comes off as snarky and unlikeable.
Sam Spade and Effie are the worst at it.
Same for comedians. Some can pull it off, some can't. Jack Benny's shows are still fresh and funny. Bob Hope's are cringeworthy.
