I totally agree but, and this is likely just my age talking, I still enjoy most of the oldies. Almost entirely on nostalgia grounds. My father was in the Philadelphia Highway Patrol and I remember watching "10-4! 10-4!" Highway Patrol sitting on the floor in front of the large B&W TV with the big sheet of glass on it. Ditto many other oldies. Like eating grandma's chicken soup. Comfort food.
As an adult, two shows I find almost painful to watch (OK, but I watch them anyway) and wonder why they have such ongoing cultural gravitas, are The Twilight Zone and Colombo.
Maybe I can give TTZ a bit of a pass because in those days we didn't have all the science we do today and the general public was even more in the dark about it. But as far as Sci-Fi, the "Sci" is embarrassingly vapid, dopey, comic book level, and that makes the "Fi" part just plane dumb because the it relies on the Sci part being plausible. It comes across more like children's fantasy stories nowadays.
And almost everything Colombo does is either illegal, and was even back then, or he's repeatedly out of jurisdiction. No real PD would operate that way. And if he's a Lt. doesn't he have an office with "regular" cops reporting to him like Van Buren in "Law & Order"? Why is he always going over people's houses and asking questions? It's called harassment. Either take him downtown or fill out the report and call it a day.
