Marian64’s review published on Letterboxd:
yep, as good as one of the better Black Mirror episodes!
After being pleasantly surprised by his adaptation of The Invisible Man,
I wanted to check out Whannel's other work which includes this and an Insidious sequel. This film confirms he's an indeed more than competent new director to watch.
Another solid film to add in the "DONT THINK YOU CAN CONTROL/ TRUST FUCKING COMPUTERS DAMNIT" category.
