Just got round to finally getting to start watching The Snowmen... minor quibble to start off.
I don't like the titles. Matt's face in them is hokey as hell - sure it's a 'classic who thing', but it should've stayed in the 80's, where it belonged! And whilst the theme tune has lost a lot of its bombast, it's pretty good - it's 'retro' in the good way, unlike the Face thing.. I'm glad they've kept the opening to it that started in 2010, too. But the visuals just look a little... I dunno. Maybe I need to get used to them, but I'm not a fan yet.
Any spoilery stuff I'll put in the reply when I've finished!
