Well, that was truly event television! Packed with beautiful fan moments, The Day Of The Doctor was a love letter to both Doctor Who and its loyal followers.
While the main plot revolved around "The Moment" (the sentient WMD The War Doctor - John Hurt - was to use to end The Time War, that manifested itself as an image of Rose Tyler) as the daleks and Time Lords battled it out on Gallifrey, there was a brilliantly interwoven sub-plot about a zygon scheme to take over the Earth (from the 16th Century).
This was Steven Moffat's crowning glory, by a fan for the fans; peppered with clever nods to old stories, without slowing down the constant kinetic energy of the central teaming of The Ninth and Tenth Doctors with their suppressed forebear.
All the past faces of The Doctor got a look in and we were even treated to a glimpse of the face to come.
At the moment The Day Of The Doctor stands review-proof. It's been too long since I've come away from an episode of Doctor Who grinning so broadly and so fired up with fan-boy glee.
To be honest I can't wait to see it again, to pick up on moments I might have missed, and I'd love to see it in 3D to see if the Gallifreyan art - and the Time War sequences - look as spectacular as I imagined they would.
However, not only was the episode superb in its own right, but the major new arc it opens for The Doctor to pursue, going forward, will hopefully herald a new burst of positivity in the show's creators as he embarks on this new quest.
