I guess you never know what to expect with the team of writers/directors/producers that are involved in this show.
But in my humble opinion they have exceeded every expectation.
Not only i think its the best episode in the series but in my humble opinion is one of the best in TV history. If you take all aspects into account you will realize that the episode was truelly epical.
They managed to have every active ( not dead ) Character in the 90 minute show. The action the drama the suspence was overflowing throughout this episode. The actors did a phenomenal job too. The casting is great we already established that since season 1. Every Character is a hero in its own special way and this has been perfectly represented in this episode.
They also managed to give answers to many questions yet they created a new series of expectations and uncertainties.
I dont think i was so intrigued by Tv series since Twin Peaks.
I cannot wait for next season and i hope that it ends in the Grande way that its suited for it.
