Holy fuck. THAT. EPISODE. I've never seen anything like that last 10 minutes in a television show ever. SOOOO good.
Well, to be fair, X-Files did an episode called Triangle.
Directing style
Filmed in real time, the episode is designed to look like it was recorded in four uninterrupted eleven-minute takes.[12] Carter explained, "I said [to the cast and crew] 'Wouldn't it be great since we have 44 minutes of programming time if we just did an episode where we did four 11-minute takes and put it all together?' And everyone looked at me like I was nuts."
