This is a movie with a clever premise, very likeable lead character and some very funny moments. It's difficult to settle into as the narrative is constantly rewound to encompass different scenarios and, like lifelong mental illness, doesn't leave one feeling everything is fully resolved. Tyler has a mental illness where he vividly imagines negative outcomes to things that are about to happen. This leaves him in isolation and unable to effectively respond to daily occurrences. He works with a therapist to try to become more functional. Since he is attracted to his neighbor, the jogger Shane, his therapist encourages him to planfully try to get to know him.
