Great news! My one qualm with Fringe has been the excruciating set-ups for the first half of each season, so I am actually preferring the news that we will get a final half-sized season as opposed to a full 22 eps, as I see this will mean we will get far more action and plot twists with nothing getting dragged out over various episodes.
This is GREAT news! Woo-Hoo! I now know I will buy the complete series on DVD next year as the show will have a proper and complete conclusion to the overall stories of the series.
