The One I Love starring Elizabeth Moss (Peggy from Mad Men) and Mark Duplass (Pete from The League). I was initially drawn to this movie because I really like the two leads and the reviews were good. I didn't dig much deeper than that before renting it on Vudu. The movie was nothing like I expected it would be, in the best possible sense. There's really no way to talk about it without spoiling the shit out of it, but I LOVED it. Highly recommend it and the less you know going in, the better IMO. It's available on all the major streaming services.
