Our Take: Current Doctor Who showrunner Steven Moffat wrote “Joy To The World”, and it has Moffat’s signature sense of whimsy and light slapstick. It’s a bit light on actual story, though; it feels as if this holiday episode is designed to be more of an exercise in showing how good the show’s VFX have gotten over the years.

Disney Plus will stream Doctor Who: Joy to the World on Wednesday, Dec. 25, at 12:10 p.m. ET (9:10 a.m. PT) in all regions except the UK and Ireland, where it'll air on the BBC.
