Intriguing on the surface but doesn't satisfy

Rating: 6/10 (21 March 2017)

I watched this and it starts off intriguing but then descends into a B rate horror/thriller.
What I liked :
Acting was all generally good, story starts of exciting your interest.
I did like the concept, brain surgeon and psychiatrist wife with nutty family could have created brain transplant method.
What I didn't like:
The whole black/white race issue is meaningless. Do the whole thing with mostly black or mostly white people it would probably work better. It's trying to make a race issue without any race issue.
So the mum can suddenly hypnotise Chris just stirring the tea cup - I think not.
The family/girlfriend possibly feeding Chris hallucogenic drugs perhaps, slowly building up hypnotic suggestion over several months during the relationship would have made this plausible.
But as is, just scraping a spoon stirring a teacup created a big WTF ! moment.
They could have done a lot more on the mixed personalities of the transplants without giving the game away. Instead they rapidly went to rather C grade horror, cutting off top of skulls to remove brain. Yawn.
All in all, it's not terrible, just rather disappointing.
Good build up with unsatisfying 2nd half. 6.5/10
