The Fundamentals of Caring (2016)
People love Paul Rudd! That belief alone probably motivated this paint-by-numbers mid-2000s indie ripoff, which stars Rudd as a retired writer (hah!) searching for his next chapter (get it?). After deciding to become a caregiver (yes, this plot is shaping up nicely), he gets a job from a woman whose teenage son, Trevor, has muscular dystrophy, but also a sarcastic sense of humor. When Rudd and the kid go on a road trip to see famous roadside attractions (it's one of Trevor's adorable character quirks that he's obsessed with roadside attractions), they learn plenty about each other, but -- spoiler -- just as much about themselves. Selena Gomez shows up as a love interest for good measure, so if you're in the mood for an undemanding, treacly teen road-trip flick, The Fundamentals of Caring is your Rudd-approved best bet.
