If Supernatural and Twilight were people Supernatural would beat up Twilight for its lunch money.
As for show recommendations there are plenty of very good shows mentioned in this thread, but if you feel yourself getting burned out on all the serious going on hit up Archer on Netflix. They have seasons 1-3 on Instant and season 4 is running now on FX. Just beware that Archer really, REALLY earns its TV-MA DSLVXQUL& ratings so put the kiddies to bed before viewing.
