Just saw this movie with the people from work. This was a crazy freaky movie. Very well made. Well acted (nod to the only actor receiving more than 10 minutes of screen time - Will Smith). And well written. It ended before I was ready for it to end. It only 1/2 way resolved. There is loss. There is gain. There is a freaky mannequin fetish (ok, only 1/2 way kidding).
Warning, if you or your spouse, or SO, or friend is at all afraid of the dark, or monsters, or is freaked out by zombies-ish-ness then just don't go because it won't be the movie for you.
Overall I give this the highest rank. The movie drew me in and no matter how long it lasted, if it kept up that pace & quality, I probably would have not noticed for several hours.
