Though the plot of this mismatched-buddies drama may feel overly familiar, the bold casting and watery setting provide a welcome edginess that enhances the inevitable sweetness, making it genuine. Co-written and co-directed by first-timers Tyler Nilson and Michael Schwartz, The Peanut Butter Falcon does follow a well-worn story arc, but the presence of Gottsagen -- who has Down syndrome in real life -- quickly ups the ante. The role of Zak was written directly for him, and he's instantly endearing. LaBeouf, meanwhile, is known for his irreverence and volatility, which makes it all the more notable when his character opens up and shows a softer side of himself. When that happens, it's a happy surprise -- and it's wonderfully honest.

Johnson, best known for playing Anastasia Steele in the Fifty Shades movies, completes the picture, likewise showing far more appealing vulnerability here. Largely filmed in Georgia, the movie makes beautiful use of land and sea, sun-baked shores and boats; it feels warm and open-aired, smelling like salt and fish. Yet it also conveys a realistic sense of desperation and menace, making the perils of the journey feel more concrete. In the end, The Peanut Butter Falcon shows great and rare compassion, not only for Zak, but for anyone who feels marginalized or misunderstood.
