Jordan Garren’s review published on Letterboxd:
Heather Graham stars as psychologist Dr. Elizabeth Derby, who is visited by a troubled young man named Asa who claims to have had an "out of body experience" and that his father is trying to take his body. Thinking he's schizophrenic, Dr. Derby eventually discovers that Asa's dad is an ancient entity that's been swapping its consciousness into bodies by reciting Cthulhu-speak, and now it has focused its interest in HER!
Based upon H.P. Lovecraft's short story "The Thing on the Doorstep," SUITABLE FLESH doesn't waste any time in moving things along and features some pretty great performances from Heather Graham and Judah Lewis. (Plus I have to give a shout-out to the wonderful Barbara Crampton who seems to have discovered the same elixir that keeps Paul Rudd young! Haha!) Both seem to easily swing from one personality to another as they lose control of their physical bodies, and it all builds to a gruesome autopsy and a conclusion that may frustrate some viewers.
I enjoyed SUITABLE FLESH - It's a fine addition to the handful of good Lovecraft adaptations and gets an easy recommendation from yours truly.
