This was much better than I had expected, given a simple premise and low budget. The acting was excellent and it is well-paced. It is a journey of a gentle, caregiver's descent into madness when life becomes more than he can handle. We see a kind, gentle, incredibly lonely man who spends his days taking good care of his dementia-ridden, potty-mouthed mother. The movie takes place in the 80's which is pretty cool. We watch his angst escalate as well as his loneliness. He "befriends" a man on a tape, that is how lonely he is. This turns out to not be a healthy 'relationship', as one can imagine. Things get very, very dark from there. This is very suspenseful movie, but quite dark. If you are okay with that, I recommend it.
