Funnily enough, I’m not the biggest fan of Christmas specials. There are the good ones (The Christmas Invasion is really fun IMO, A Christmas Carol is absolutely fantastic, The Time of the Doctor has its issues but I like it), but the others I’ve seen so far I’m not that big on (this one and Voyage of the Damned I think aren’t very good, The End of Time I do like but it’s also very much a mess, The Doctor, The Widow and blah blah is pretty dull and boring, and I’m not too keen on The Snowmen either, I mean the titular Snowmen don’t even really do anything).
I just think Donna is too much here and while the Racnoss is impressive visually, outside of that I don’t really like it. I also just don’t buy the Earth’s core being a Racnoss ship or the fact that ordinary guy Lance would join up with this giant alien spider queen.
It has its good moments though and, even if it is minor, it was fun to see the Roboforms (also called Pilot Fish) in the second Christmas special after appearing in the first.
