Hate to say it. But I am really underwhelmed. By no stretch did I think it was it bad but there was a lack of excitement in all but 2-3 areas.
The big problem here was tension. And usually Fringe pulls off tension really well. They understand how to up the scale, pile on the dread and maintain that sense of foreboding.
Honestly had I not seen Letters of Transit I would have been on the edge of my seat for these last three episodes. But because we knew what the future holds. As an audience member I knew this plan wouldn't succeed and there would be little fallout from this. I'm guessing they were mixing things up by getting us wanting to know how these events unfold as opposed to wondering what will unfold. But I don't think it worked on this occasion. There was very little mystery that tied these events to those of Letters of Transit.
I did like the parts with September (Although it was Rebecca Mader's character that shot him. That left an unpleasant after taste for me) and when Walter fired the gun that caught me off guard.
The thing that did blow my mind though.
It was Walter's idea and now that he's had his brain tissue reinserted in the future. I am thinking the **** is going to hit the fan. Also with September I'm thinking they dropped hints of William Bell having bigger plans with The Observers so I'm excited to see what happens there.
It was an OK finale. But by far and away this was the weakest of the four.
