I really enjoyed the Toymaker. Everything was so manic and fun but still dark.
I'm not sure I'm on board with 15 yet, the way he was going to sneak off felt odd, I don't trust him. I will say I've never liked a new doctor so it will grow but right now I'm like, nope!
But it was exactly like that when he lied to Donna and said he was going to park the TARDIS properly before coming in for dinner. Had she not called him back he was going to leave without a word.
When the doctor has done an irish exit in the past it feels good spirited, for the good of the others or for lighthearted mischief. This felt more sneaky.
