Enjoyed watching all of the season in a "fringe marithon". I find myself, with this series, addicted in going on to the next episode! The forth season was very enjoyable. The twist in the alteration of the timeline put a bit if a complicated twist on things and negates things that happened in previous episodes which I was glad had occurred. Great series especially since the first episode I watched was July 2012. Was sorry to hear that this 5th season is the last one and there will only be 13 episodes where other years had about 20.
