The fourth film in the series subs in a new wimpy kid (Greg Heffley is now played by Jason Drucker), annoyed at the prospect of a family road trip in which mum (Alicia Silverstone, but with glasses) has banned “all electronic devices”. Kids may be able to relate to Greg’s plight (I know I did), and a silly joke about him becoming a meme called “Diaper Hands” induced a loud giggle, though parents may roll their eyes at the visceral, gross-out quality of the comedy.
