I guess I should know this, but we all have our unique tastes, which can’t be accounted for. I watched Columbo as a kid, some. For me, it was okay.
I’m really not a person who goes in for humor on television unless it is quite dark, which isn’t very nice. I think that I like the late Victorian and Eduardian era that Sherlock Holmes mysteries take place in, but I had to think about it a bit to realize it.
I think humor or none or kind is largely a function of our personality type. That is my theory, anyways. But I will give Poirot a try for starters.
