Consider the ***** rating for both the finale and the series itself. My reaction immediately after the robust 2 1/2 hour series finale was: that was the best series finale I have ever seen and perhaps the best TV episode I've ever seen. There was a parade of memorable scenes but every scene was purposeful and perfectly executed. They were never going to answer all the questions.
I've been browsing the web, reading reviews and recaps and panels about Lost and this past episode, which was probably one of my favourites. Everybody's spending so much time guessing at what's going to happen on Sunday; who is going to die, who is going to survive, what will happen in the sideways reality, etc, etc, ad infinitum.
Loved this episode. Besides maybe "Lighthouse", best one so far this year. "Dr. Linus" has always been the best character on Lost thanks to the incredible Michael Emerson (and if he doesn't win an Emmy I'm going to blow my gasket!) and we got a full episode of him.
