I loved the previous episode due to its "once in a while tone change." "Roadkill", gets back to the serious tone and this one really flows well. Starting off with the episode's plot scenario and it takes off right from there with Sam and Dean right in the action. I don't want to give away too much of this episode's plot because this is one of the strongest plots of the second season that really stands out. "Roadkill" really gives off the Supernatural's creepy and suspenseful vibe at best. The plot structure is not perfect, however I still gave it a 10 because of the it's Unique Ending, and this is one of the endings that the Show that really went well and heavy with the emotions and very "Supernatural" for a reason. I highly praise this episode's staying true to the show's unique tone and the plot-turns.
