"99 Problems." This is probably one of the best teasers in the entire series. It opens with a manic moment right of the bat, the Impala being pushed as hard as she goes with Dean behind the wheel, and a bleeding Sam sitting next to him telling him to go faster when it's clear they can't. Enter the fiery roadblock and then demons yanking them out through newly broken windows (poor Impala!). That opens up the golden opportunity to be saved gallantly by a Sci-fi icon. Yep, what a way to open an episode! Too bad it turned out to be the only excitement in the entire hour. It felt like a Smallville episode.
