Craig Roberts and Paul Rudd in The Fundamentals of Caring.

Netflix original movies are popping up more and more—some with big stars in them. For example, The Fundamentals of Caring stars Paul Rudd.

It’s not a bad movie at all. It’s actually almost good—but not quite.

Rudd plays Ben, a distraught, grieving novelist mourning the loss of his son and going through a divorce. In order to get himself out of a rut, and perhaps start writing again, he takes a course to become a caregiver. He gets a job caring for Trevor (Craig Roberts), a young man suffering from muscular dystrophy who doesn’t have long to live.

Trevor is a bit caustic, and the two men develop a strange sort of antagonistic friendship. They wind up on a road trip during which they pick up Selena Gomez, who curses a lot. Road-trip wackiness ensues.

The Fundamentals of Caring uses all of the familiar road-trip tropes; unfortunately, Gomez takes the movie down a notch. Rudd and Roberts are pretty good together onscreen—almost good enough to make the movie worthwhile. But in the end, The Fundamentals of Caring is an uneven venture—which is surprising, considering Rudd’s involvement.
