I think I watched Richard Belzer's performance as Detective John Munch in Homicide: Life on the Street ('93 to '99) and the Manhattan-based Law & Order: Special Victims Unit ('99 to '13), but for some reason I can't recall any takeaways. What this probably means, in all fairness, is that I didn't find Munch an especially rich or compelling character. Amusing, yes, but in a sidelight fashion. Mainly he struck me as compulsive.
