MSNBC has their list of top ten monster shows and Supernatural is included:
'Supernatural'
Now in its sixth season and showing no signs of fading away, “Supernatural” tells the story of the easy-on-the-eyes Winchester brothers. Well, more to the point, it’s the tale of a couple of good-looking guys who also happen to hunt and battle demons, spirits and other monstery whatzits on a regular basis.
While “Supernatural” doesn’t rank as an instant classic like some of the best-of picks, it’s easy to get caught up in the drama of the second-generation ghostbusters story.
Also, if it hasn’t been mentioned yet, those Winchester boys sure are attractive.
