This is the creepiest episode in Season 2. This has the most suspense because you won't know what's really going on and who else in town is going to turn against you. You can't get out, you don't know the cure.
This also has lots of mysteries hanging. What happened to the townspeople in the end? How did the virus started in town? And finally the cliffhanger at the end where Dean tells Sam what their dad told Dean at the first episode of the season.
The isolation of the town was also well illustrated. It was cold, rainy, and all you can see around are trees. With only one road going in and out of town, I'd panic if I was in that situation. Great episode.
