Supernatural had a pretty good season opener although I think it crammed a bit too much into one episode. As of last season, Lucifer has been loosed upon the world, angels and demons are spoiling for a war, and Sam and Dean stand in the middle. It was nice to see the return of Chuck the pulp horror writer prophet and the the wickedly demonic Meg, now played very well by Rachel Miner (Dani from Californication).
If these two shows keep it up, I suspect my Thursday nights are spoken for.
