Hannah Long ن’s review published on Letterboxd :
Easily the best Christmas special so far, a whimsical mixture of Dickensian atmosphere and fantastical creatures (the scifi is almost an afterthought). Matt Smith, always good, is terrific here as the Peter Pan-esque Eleventh Doctor, and Michael Gambon puts in a solid guest performance. The only weak link is Abigail, who is just good, but whose voice makes up for it. A lovely story, one of my new favorite episodes.
