I watched it in disbelief, and watched it again at 4:00 a.m. It is a brilliant ending. We saw a slice of Tony Soprano's life...we never saw what went before and maybe (unless there's a sequel or a movie) we will never know what happens to Tony. For sure it will keep us talking about him.
This is the best scenario of the ending I have read and I agree. While we were in suspense of what would happen in the last minute or so, we truly saw and felt how Tony lives each day.
Looking at every individual with suspect, never knowing where or when it may come from. The good times with the family are too few and to far between, but the struggle of trust, deception, and deceit are always present in Tony's world.
