In 1992 The Doctor encounters an 8 year old boy named Grant (Logan Hoffman) while installing a device on a roof to help repair damaged that was caused when he last visited New York City. During this encounter The Doctor gives Grant a wish granting gemstone to hold which is used to power the device. Grant mistaking the stone as a cure to his cold swallows the stone. The stone gives Grant his wish of having super hero powers.
Returning to New York 24 years later The Doctor investigates the research company Harmony Shoals while doing so he encounters Lucy Fletcher (Charity Wakefield) who is an investigative journalist also looking into the company. Grant ( Justin Chatwin) is now serving as Lucy’s nanny and helping to look after her baby girl while leading a double life as the super hero known as The Ghost.
Together they all try to unravel the mystery of Harmony Shoals and what they are truly doing
Doctor Who Christmas specials I tend to find can be a bit of a hit and miss thing. For example last year’s entry The Husbands of River Song I thought was a great special (review for that can be found here https://downundergeek.wordpress.com/2015/12/28/doctor-who-the-husbands-of-river-song/) While on other occasions they can be not as strong. This entry to the list of Christmas specials fall about in the middle of the road.
The acting on the whole was reasonably solid throughout the episode with Justin Chatwin, Charity Wakefield putting in good supporting roles. Peter Capaldi had some great moments and some good comedy to the episode. The main setback for the cast was Nardole (Matt Lucas), while his performance was good I felt the character did not fit in with the story that well and did not really contribute much to it.
The main down point for me is it felt very similar to other things Moffat had done before and was not really breaking into any new territory . While it was not a bad episode it does show the tiredness of his time as show runner. Hopefully the coming change for series 11 will bring a breath of fresh air into the show.
Having said that though I did enjoy how this special tied nicely into the previous one referencing the 24 years spent with River Song which was a nice way to tie up that story and also the fact we have not had any Doctor Who in 2016.
While not the strongest Christmas special it is not the worst. I would say it sits somewhere in the middle.
