At the end of a very middling season, Supernatural managed to go out in a blaze of glory with Sacrifice.
The episode opened with the Winchesters seemingly capitulating to Crowley's demands and giving up on the trials only to turn round and trick the ultimate trickster by making him the subject of the third trial ("to cure a demon").
Meanwhile Naomi and her goons swooped down on Cas and Metatron - in the midst of their own series of trials - only to discover that Metatron has been working to his own secret agenda all along.
Throw in an appearance by Abaddon and Sacrifice has more going for it than a handful of previous Season Eight episodes all smashed together.
The episode also left us on a mighty cliffhanger with the fate of the major players in the Supernatural universe (e.g. Sam, Dean, Cas, Metatron and Crowley) intriguingly unclear.
Finally, we got an episode truly worthy of the Supernatural brand, but what a pity it was the season finale.
Hopefully Season Nine will see a return to form and a proper addressing of the many sub-plots thrown up arbitrarily this year and left dangling (such as the whole Men of Letters deal, The Thule Society etc).
Although I think it speaks volumes about Supernatural that even a comparatively weak season such as this still averages a score of over four out of five in my Enjoyment Ratings Average system.
You just need to check the page with the links (which hopefully still work) to my reviews of all eight seasons of Supernatural to see that while this season was the show's lowest rating to date (an average of 4.04) that still puts it ahead of most seasons of Doctor Who since that show returned in 2005 and well ahead of the first two seasons of Merlin.
I'd take a shaky season of Supernatural over a Moffat season of Doctor Who any day of the week (although to be fair, it is a somewhat chalk-and-cheese comparison).
Meanwhile, here's a handy (and spoilerific) guide to all the tablet shenanigans in Supernatural's Season Eight:
