This one is interesting, because it's not made for you. 

Doctor Who at it's most domestic and arguably commercial. This is designed as pleasant and unobtrusive entertainment, and it hits that mark of what it's trying to do admirably, it entertains. But this is television that you're sort of meant to find hopping between channels and keep it on as a lark, watching the funny alien man try and be apartment friends with James Corden. Most Who fans will find that pitch a teensy bit agonizing in a way, their hero reduced to the barest sitcom pop culture components. Dr Who on the third rock from the sun. Dr Who does ALF.

But also, show this one to a non-Doctor Who fan (as I have several times) and they'll almost definitely have a grand old time. I admire The Lodger's efficiency, if anything, but it's just genuinely an oddity that it's hard to get much substance from.
