Doctor Who: The Snowmen episode

"To be honest, I often have no idea what is going on in Doctor Who, but it doesn't matter. And this – by Steven Moffat himself – is a lovely one. It is as if he has got every idea he has ever had to do with snow and Christmas and cold, and a some other ideas, and stuff from other projects, Sherlock Holmes even, put it all in the snow globe of his mind, and given it a bloody good shake. Watch and marvel as it (sort of) settles." 

"Hang on a minute, I thought the gather-ye-round Yuletide edition of Doctor Who, The Snowmen (BBC One), was supposed to be the scariest ever? (...) [Moffat] didn’t have the legs needed to transport us to a state of breathless excitement (...) t was an enjoyable enough romp, I suppose."
