I'd give the werewolf episode a 5 out of 10, I guess.
Not only is it cheesy, with bad acting (the sheriff, especially), it's so predictable.
- Bartender is a werewolf and sends victims to her hunting grounds
- Burly security guy is also a werewolf. Looks at them weird when they leave.
- Kid they save has been bitten. He kills Sam.
- Oh, no, Sam isn't actually dead. Dean almost dies for nothing.
- Guy turns in hospital.
Werewolves in Supernatural have never really been great.
