FX was smart and decided to extend the fourth season of Sons of Anarchy. This season has been the highest-rate yet, so it was definitely a smart call on their part.
Creatively, this has been Sons' best and biggest season ever. Kurt asked us to consider adding an extra episode to fully close this current chapter of the Sons saga. By adding the extra episode, it wraps up a magnificent season in extraordinary fashion. This is a real bonus for fans of the series.
The season finale (episode 14) will now air December 6! Nice!
