DOCTOR WHO
BBC America, 9:00 p.m. ET
The two-part opener of the modern era’s Season 9 was another cleverly constructed, twist-filled Doctor Who. I’d say “surprisingly” as well as “cleverly,” except that this series has been so consistently imaginative and enjoyable, it’s no longer surprising that it delivers. And on this show, very little is what it seems to be at first glance – including, tonight, even the very environment of an imperiled underwater base of operations.
