I got sucked into "Supernatural" by some of my friends because they were such big fans. I liked first season as it had a good story arc and some interesting delving into Urban Myths. It also develops the characters and the family pretty well. 2nd season is a different beast. It's a bit more ... revisionist I think. It has more fun poking fun of itself and the genre as a whole, but it has some GREAT episodes. I'll be curious to see what you think of it as you watch the rest. ;)
