Read first, or watch first?
Read first — and for once the book is not the bigger ask. Rip runs about an hour read aloud, less if your kid reads it alone, against a fifty-minute film; the two cost a family roughly the same evening, which is not true of a single other book on this site. Do it in the other order and the film hands over its ending, which is the only surprise the story has. The adaptation is worth chasing afterwards for Harry Dean Stanton, who plays Rip as genuinely sweet rather than merely lazy, but chasing is the word: it is a 1987 television episode sold on disc, not something waiting on a streaming tile. The Claymation short from 1978 is the other good one, and it is currently easier to find in a library than to buy.
