Stop Holiday Nonsense **1/2
2 November 2013 | by (United States) – See all my reviews

Every time this series goes with the holidays, we soon find ourselves stuck with eerie nonsense with a miserable script tagging along. This episode was absolutely no exception to the rule.

A maniacal doctor wants to operate on a bad adolescent, courtesy of his father paying for this nonsense. We hear about cysts on the brain and all sorts of horrors. Our lunatic chooses 2 innocent victims to practice on.

I don't have to tell you the consequences of that one.

In a brief sideline, Steve's girlfriend is warned by him that for her own sanity, she had better come to grips with Billie's death and move on. Very good advice.

They're still looking for Adam. No Kono in this episode. Finish that part of the saga already.
