It is well done. The whole movie has an intentional creepy feel. That kind of keeps you engrossed. Fairly simple, but non-obvious storyline. I wasn’t sure what to expect. But, I am glad I watched and it kept me engaged. A great study of an autistic personality.
I liked it. If you like dark, taut murder mysteries — purposefully shot to be slow-paced — you will enjoy this. I watched it, free, on Amazon Prime. But, it is on YouTube too.
