The season finale of Lost was basically the most amazing two hours of television I have ever experienced. Almost literally every five minutes I was jumping up and down in my seat and shouting at the TV.
Considering how so many people felt this season was really weak at the beginning, it has been pretty much non-stop amazing for the past...oh, eight, nine episodes? and ended with perhaps the strongest episode ever (which I'm fairly sure I'm saying without exaggeration at this point).
It's a long wait to '08, lads.
P.S. Props to my BFF Slade on totally half guessing one of the big twists of the episode.
