This is truly an excellent horror film.
I just watched it for the first time today. And the IMDb rating of 6.8 is far too low.
There's a family in our driveway. I also have to say that I laughed out loud when the shadowy doppelgänger family was standing in the driveway. The father's terrified reaction was hilarious. And I say this as kudos to the film. I was thoroughly entertained on more than one level.
The little boy playing a dare game with his clone was also well executed. That child actor has a promising future in film. Much respect for Lupita Nyongo's performance as well.
Great film. I highly recommend it.
