Very Good But...
The only flaw for me is how quickly they all accept the ludicrous premise that there's a house down the street with their dopplegangers in it.
I get, for the sake of narrative, that they needed to get on with it but I think it could have been handled more effectively.
The opening twenty minutes are gripping and I would have liked to have seen more of that. Great performances all round.
And the film was intelligent.
