And definitely a disappointment, as others have pointed out. It basically made nothing out of nothing. Very incoherent. Put "Altered States", "Alien", and "Ten Little Indians" into a blender and this is what might come out. I felt better about it the day after -- some interesting ideas (the book is supposed top be better) and halfway decent production values. But all in all a two-star (out of four) movie. I liked Jennifer Jason Leigh, and Natalie Portman was OK, but overall the whole thing was pretty week. Scarlett Johanson's "Under the Skin" from 2013 was certainly bizarre and didn't give much in the way of explanation,, but by comparison was an excellent movie IMO.
