I oddly enough had a ex girlfriend who loved this show.

Seasons 1-5 were great, it should have ended after that as it was the original and fully planned 5 season story.

Season 6 and 7 had weak villains and very corny also. The storyline in season 8 brought back attempt at a more important story but it just seemed to jump the shark especially its final season when God himself was the new big bad. It just was ridiculous.

Also the writers in later seasons didn’t care about sticking to cannon at all and many aspects of the lore would just get retconned.

It’s a shame because the Actor played Dean could have been a A list movie actor it the show had ended after 5 seasons in 2010. Rumor is he was first choice for Marvel’s Captain America but he couldn’t do it with his tv show duties. Now he’s too old to likely make it to the A list in movies.
