A beautiful film! Sean Penn's character, Clark, applies the wisdom gained by experienced cab drivers and bartenders who trade personal stories about their lives with customers who offer theirs in return; both of whom understand that their temporary relationship affords a depth of trust that is rare in relationships. His rider, played by Dakota Johnson, in just a couple of hours finds the father she longs for and still needs, but never had: a man both supportive, encouraging and lovingly critical, yet humble enough to accept correction and even rebuke graciously. When he offers her a handshake on the sidewalk in front of her home, she instead reaches her hand out to caress his cheek. One can bet she will look him up at his cab company again for the parental influence she needs.
