How about that "Lost"?
Bang, boom, bust! And Ana Lucia is down.
There was a lot, a lot packed into that last five minutes. We had Henry Gale's Col. Kurtz-ish references to the Others' leader. We had Michael going native and releasing Henry, after shooting Lucia and Libby (who I'm guessing is not dead -- nobody in a TV show gets shot in a blanket wrapped around a mysterious object without that mysterious object stopping the bullets). And did you catch the random commercial for the Hanso Foundation thrown into one of the commercial breaks? Everyone else here seems to have missed it.
My only complaint is that the show crammed so much stuff into the first new episode after a bunch of repeats that I wasn't fully invested in the characters again. It deadened the shock a little.
