Well...this is awkward...
I was kinda excited about this episode...it wasn't set in London or Cardiff, The Doctor had to act Human and he had to share a house with James Corden!
But by the end, I felt a little...disapointed. Some stranger had been bringing people upstairs to a 'Flat'...and they disappear. But then we go upstairs to find out that "someone has built a TARDIS"...wait, WHO?
They forgot to tell us!
Or maybe it will be explained in the next episodes. I can't wait!
