“The Lighthouse” picks up where “When the Bough Breaks” left off. There’s a disturbing glimmer in Audrey’s (Emily Rose) eyes as she places her blackened hand upon Duke’s (Eric Balfour) chest to re-trouble him. Maybe it’s just me, or maybe I’m greedy but I expected more from this season finale—with it being a two-parter, no less. Don’t get me wrong, the mind-boggling ending is an absolute doozy. Lives are at stake, and that makes me worried for what could happen in season five (which has yet to be formally confirmed). My four star rating is mainly based on Colin Ferguson’s brilliance in his portrayal of William, and for the strange events leading up to the final scenes.
