One of my all-time most favoritest favorite shows (the original series, didn't care for any of the reboots, the writing wasn't nearly as crisp, something that Falk himself acknowledged). This was, by far, the finest crime show of its era. Falk's characterization is legendary; the famous guest stars, the clever dialogue, and those intricate plots, with Columbo honing in on the killer, usually very quickly, then annoying them to no end, and finally that "gotcha" moment when he finds the goof that trips up the bad guy. I've watched them all several times, though not in many years. May be time to go through them again. A show ahead of its time, it would fit right in with the "New Age of TV" these days.
