Screen Rant

Supernatural is ending with season 15. 1 / 7

Some say it should've concluded sooner... 2 / 7

But then characters like Castiel wouldn't have developed as much as they have. 3 / 7

Supernatural has continued to expand its boundaries to find new material. 4 / 7

But this can only go on for so long. 5 / 7

And Ackles and Padalecki no doubt want to explore other roles. 6 / 7

There's also no villain that could possibly follow God. 7 / 7
