This episode reminded me of a really bad scary movie - the horrible acting, the actors "filming" the action as it happens around them, and the one actor living at the end with the knowledge of what happened.
The episode looks just like a youtube video. A really bad youtube video that I turned off after five minutes because it was so boring, and horribly put together. It was just like a Ghostfacers ripoff, but at least we had the prank war and actual scenes with Sam and Dean.
It had so little to do with anything that I should have just skipped it.
Basically, I've seen much better episodes of Supernatural.
