Why not a film or series friend? Is it difficult to do beacuse of the book content - or chance of ‘messing it up’?
Messing it up.
Part of the charm is it’s 1950s (or earlier) sensibilities and dialogue. No way those things make it intact in any modern adaption. Can you imagine a modern adaption of Star Wars today in which Han calls Leia “sweetheart” or the scene between the two on the Falcon where they first kiss? No way those things make it into a movie today.
