Colombo

I just purchased the complete series DVDs and have begun watching. I had forgotten what a great show this is. It's quite interesting to watch as Falk develops the character over time into the iconic Columbo we all remember. In the earliest shows he not as much the sly and subtle adversary lulling the suspect into feeling he can evade justice by outsmarting him.

The "how's he going to nail him" rather whodunit approach also makes the show more watchable multiple times than many mysteries where if you remember the culprit it spoils things. It's a lot more difficult to remember how he figure it out and confronted the killer than it is with other shows to remember who did it.
