Joaquin Phoenix shines in Ari Aster's haunting 'Beau Is Afraid' review.

Director Ari Aster's latest film, "Beau Is Afraid," follows the titular character, played by Joaquin Phoenix, on a surreal and violent road trip to confront his intimidating Jewish mother. The film is a mix of horror and comedy, with Aster poking fun at a hapless man-child crippled by guilt, shame, and countless other neuroses. While the film has some entertaining moments, it's an uneven collection of sketches that feels too long at three hours, with a frustrating and anticlimactic ending.
