This is a hard one to discuss. There are reasons to see this movie, but it isn’t ultimately for the story. Rather, you see this for the performances.
Christopher Plummer (Remember) sheds all of his typical uptightness and let’s loose with a morally reprehensible character who is also funny as hell. Vera Farmiga (The Commuter) as his semi-wannabe-estranged daughter manages to present the conflict of an ignored and abused child-now-adult dealing with the fallout. And as her son, Lewis MacDougall (A Monster Calls) creates a third generation casualty of the same. The dance between these three is the movie and is just as often disturbing as it is amusing. Around them are a collection of other interesting characters which they bounce off of during a most unusual road trip.
The issue with this movie isn’t that it isn’t entertaining, it is. And I will warn you that I am possibly giving away a bit here: It is also some of the worst wish-fulfillment and glossing of issues I’ve seen in similarly talent-laden movies. Real issues are brought up in the story. Real moments and confrontations occur throughout. But, somehow, that all gets forgotten or forgiven with barely a blink. Honestly, I kinda had to grit my teeth through the fairy tale ending and final cascade of shots. Writer/director Shana Feste (Country Strong) should be banned from creating scripts until she learns how to really commit and tell the story she intended (laughs, warts, and all) and not wimp out. There was a different road that could have been taken and that still could have been redemptive.
So should you see this? Yes. See it for the main actors and their supporting cast. There are some really good and complex performances. Just be prepared for a less than genuine resolution.
