I grew up on procedural shows because that was pretty much all there was in the early days of TV. But now I'm hard pressed to think of any that I watch -- I guess Silent Witness falls into that category, although they always take 2 episodes to solve things. Oh, and Star Trek Strange New Worlds, I guess. I used to be a big fan of the CSIs (mostly CSI:NY), and the early years of Law and Order (before it had any additional categories to it) but now I very rarely watch any US network TV shows. However, later this month, there is a new Law and Order series starting up that I will check out if only out of morbid curiosity: Law and Order Toronto: Criminal Intent (apologies if the video is region-locked). Just to see my home town playing itself rather than standing in for "generic US city".

Also, a major problem (for me) with procedural shows is that they don't binge well. A few times I've heard about a series other quite liked, and was already 2-3 seasons in, so I'd start bingeing it to catch up. The sameness of each episode become really glaring and boring really fast.
