Really good watch, would watch again, and can recommend.
The concept of living a life without "joy" is intriguing, but it doesn't feel like a very cinematic story as a concept. The movie takes great pains to try to compensate for this. I believe the casting definitely helped here.
And sure I understand guys fainting at the thought of being with Morena Baccin, but I'm not about to kick Melissa Rauch out of bed either. Both ladies brought their abilities to the roles excellently.
While the movie is fun, the motives are rather crossed and you're forced to try to think a bit more than you normally would as the story lends towards you thinking like he thinks to understand a bit better.
Overall a great little love story though.
