Supernatural is crazy because (in my opinion) the first three seasons are the best. I think the episodes and storylines are better. The costuming and the overall vibe is better. I also think Jared’s acting is much better in the early seasons. (Again in my own opinion). Except I like the characters introduced past season 3 much better. (Other than Sam and Dean). Cas is my favorite character. I love Charlie, Gabriel, Jody, Donna, Garth, Kevin, Rowena, Crowley, Eileen ect. The characters are really the only reason I kept watching the show. I’m not a big fan of the characters from seasons 1-3. I hate John Winchester. Joe got on my nerves, Ellen was alright, and I hate Meg. There was Bella who did slightly get on my nerves. (And that was kind of the point) However I do think if they hadn’t killed Bella off so soon and actually did something more with her character I would have loved her. I also just I love Lauren Cohan and think she fit well in the series. A bit part of the problem with the characters from seasons 1-3 is the writers just not being able to write female characters. (IMO)
