Unexpected but Exellent film

Rating: 10/10 (28 January 2019)

I've just watched this on film 4.
I wasn't expecting much to be honest reading the Info in the tv guide, maybe anoher people under the stairs or collector movie but I didn't expect to be gripped like I was all the way through.
Really enjoyed it and totally surprised, great thriller and exellent main actor as the blind guy.
