Fringe - 4.19 Letters of Transit

It's 2036 and the Observers have taken control. The Resistance finds Dr. Walter Bishop in amber.

Seven out of ten.

It's insulting for series I've watched for four years to start an episode with a text explanation of unseen events - they should have shown it to me or just dumped me into the situation and let me figure it out as they told the story like at the start of the third season of Battlestar Gallactica or the Fringe episode where Peter was dumped into the future.
Somehow the Observers as bad Nazi caricatures seems too easy and lazy writing. That Etta is Peter and Olivia's daughter was pretty obvious from the start.
