I am not going to watch it. The first 2 seasons were great, last one was bad. I barely finished watching it. I am very disappointed at both 24 and Prison Break last season.
I do not think Fox has any other way to do it. Stretch the story until... wherever it takes them. The script looks like is been developed on the set. This one should have ended on Season 2. Give it a rest and RIP. But Fox has nothing else to show after their shows have been a failure.
