--It was longish, and had crazy Rambaldi stuff going on, which I always liked.
--People died. Sloane died and came back to life, which was freaky, but gave Jack Bristow the ultimate and fitting death: blowing up the tomb they're in, dying to trap Sloane, immortal but buried, forever.
--Moment that killed me: Jack, lying on the ground after having been shot in the chest, tells Sydney to go stop the evil plan and won't take no for an answer. Then he *stands up*, tall and straight, while Syd and Vaughn take off to save the world. Then his legs give way and he just drops. *luvs Jack*
--It ended in traditional (and suitibly-Alias) fashion by showing us Syd and Vaughn off on a hidden island with their two children...and Dixon showing up to ask them to help on an op. LOL.
--The one bad thing: character assassination of Irina Derevcho. She's always been a very complex character, and I was sad to see her treated as just another power-hungry Rambaldi follower. I was rooting for Sark to tell her, "Jack Bristow is dead," so we could see her react--I may have to write a fic just to retcon this part of the story. *sigh*
All in all, not a bad way to go out, but not brilliant.
I know a lot of people are weirded out by this episode, but I loved it. Normally I detest "it's a dream" scenarios, but this one actually worked. House's biggest fear is that he won't be able to tell what's real, that his decisions will have consequences he didn't intend because reason no longer functions for him.
Several "Holmes"-type references: the guy who shot him is named Moriarty. At one point House tells his team that "it doesn't make sense...so what *does*" which is a totally paraphrased version of Holmes' famous line, "When you have eliminated the impossible, whatever remains, however improbable, must be the truth." And the patient's wife, in House's head, accuses him of enjoying the show-off of watching people and then impressing them with his insight, which is totally what he does, but it's a very, very Holmsian trait.
One finale left--LOST, tonight.
