I’ve been binge-watching old episodes of Poirot (via Amazon Prime) recently. I haven’t seen the early episodes since they first aired, and I probably haven’t see all of them, since I (of course) didn’t have a DVR in those days.
The series is coming to an end now, after about 25 years. There are good write-ups on it at NPR and the NY Times. I don’t think I’ll be signing up for Acorn TV just to see the last few episodes. I’ll wait until they show up on PBS (or possibly Amazon Prime or Netflix).
