If it wasn’t already taken, GET OUT would have been a very appropriate title for the new screen fever dream by Darren Aronofsky. As it stands, the fact that “mother” (lower-case) is the way Jennifer Lawrence’s heroine is billed in the closing credits, while her husband played by Javier Bardem is identified only as “Him” (upper-case), speaks to a religious subtext that’s just one of the allegories boiling under the film’s increasingly unhinged surface.
