I’m watching Columbo for the first time and I like it a lot. I’m four episodes in and even if the direction and writing have aged a bit, it still holds up very well. I haven’t watched or read much detective stories and I thought they all were “whodunit” stories. But in every episode of Columbo, you see the crime being committed in a very detailed manner, and only then Columbo enters. The whole game is how the criminal will fall, not who they are, or why they did it.
