It’s always sad to see a great show quietly end its run with little or no fanfare. Case in point: A&E’s Bates Motel, which will have its series finale tonight at 10 p.m. ET. Oh well, at least we had five years of this fun and always fascinating chiller. That’s four more than I expected it to get when I first heard about it. A series based on Psycho, for many the scariest movie of all time? Told with the same characters but in the present day – a time when digital media shines light into even the darkest corners of peoples’ lives and ensures that privacy is a rare privilege and that no secret is safe? What were they smokin’?
