Granted, Supernatural is not one of my favourite shows, but i do enjoy it nonetheless. I particularly enjoyed the first season, as i felt it was very episodic and each individual episode had a general story that started and concluded within the forty to fifty minute timespan. I also enjoyed how some episodes just had that hint of the general plot of the season in them (such as Sam and Dean's father returning in the ep when they hunt vampires) that ultimately led up to the cliffhanger ending of the first season.
