Sons of Anarchy has always seemed to pride itself on having the twistiest of plots, and “Playing with Monsters” played right into that. The issue is, episodes like these cut deeply into character development time, which last week’s great “Toil and Till” thrived on. But “Playing with Monsters” also showed how Jax’s single-minded devotion to taking down the Chinese is making things very, very complicated on the street. Meanwhile, the person who was really responsible is the one he is working so hard to defend. Hit the jump for IMDB information on Stankenstein.
