The Sgt. Wilson question has come up several times here. U either love his character or you hate it. I could maybe have taken one or two more episodes with him on it but that would have been about it. Maybe he would have even had a different first name the third time around; we'll never know.
The Wilson character I always found irritating. He was trying too hard to please, like a small dog that grabs hold of your trousers and won't let go. If I were Columbo I'd complain until the beams of City Hall shake.
