The Fundamentals of Caring is an offbeat comedy/drama starring Paul Rudd as Ben, a man attempting to overcome tragedy and looming divorce by becoming the caretaker for a teenager with muscular dystrophy named Trevor (Craig Roberts, Submarine). The two develop an unconventional relationship based largely on sarcasm and profanity, delivering many laugh-out-loud moments, while also slowly exposing the pain each is carrying inside. They eventually embark on a road trip across the western United States, at Ben’s urging, in order for Craig to see something of the world beyond his wheelchair and television. It’s a formulaic yet fun and touching road movie that covers much familiar ground, but also offers a fine illustration of caregiving, personal growth and emotional healing. Paul Rudd is as good ever, and Roberts is utterly superb. An undeniable winner, all-in-all.
