One show I've been watching this summer is MI-5 on BBC America. You can tell it's a few years old because the bad guys are mostly anarchists and Eastern European smugglers rather than terrorists. Also, they have not yet done a show about someone poisoned with polonium unlike, oh, every other police show in the past year.
Last night's episode featured Hugh Laurie as a posh, uptight MI-6 agent. It's funny, because I so thoroughly associate him with House now, that when I see him as a Brit, I expect him to be Bertie Wooster.
