I could mute the volume and still enjoy it. This series of DW has been so visually appealing, from the deserts of Utah, the scrapyard of broken Tardises in the pocket universe, the Portal-style kindness centres, how colourful Demon's Run looked, to the winter forest with spirit bobbles.
For the record:
A Christmas Carol > The Christmas Invasion > The Runaway Bride > The Doctor, the Widow and the Wardrobe > The End of Time Part 1 > The Next Doctor > Voyage of the Damned
ACC was clever, TCI was epic, TRB was funny, it's hard to narrow down the bottom 3 since they're all so poor and feature scenes such as the CyberKing, the Master in drag, and a episode which tried to tug the heart strings that had two fatties falling off a ledge.
