I didn't like that Bobby's death felt anticlimatic. That's how it felt to me, it should have been done better. Bobby was a fantastic character, going to miss him. Season finale was pretty weak too.

One thing that I'm hoping they do for next season is bring back some of the monsters that Sam and Dean have killed. Dean and Cas are in the place that they go once they die, so maybe we'll see some of them again. Maybe like Gordon, the werewolf chick, and maybe even Bobby since ghosts are monsters. It would be a shame if they miss that opportunity. And yeah I do want Gordon back.

Hawkeye was in Thor. It would be great to have Coulson around still.

That is pretty dumb though, why would you have a button to release all of the monsters? Same thing happened to me, there was only like three other people in the theater too.
