It's mostly carried off with aplomb, particularly by Charlie Wright, who looks like a slightly less evil Ezra Miller and gives a genuinely funny performance as permanently perplexed metalhead Rodrick.
A dirge of unfunny scatological material, techno-anxiety and child endangerment masquerading as familial bonding.
It's a toxic misstep from a once-reliable series.
"Diary of a Wimpy Kid: The Long Haul" is the common type of road trip movie, the one where everything that can go wrong does go wrong.
The all-new cast is fine, but this "Wimpy" entry feels skimpy on jokes and charm.
A deeply unfunny family road trip film that has gross out jokes to rival the R-rated Vacation remake.
For all the gags, Rodrick's staggering dumbness and enough poop jokes to keep the average kid happily chortling, this Wimpy Kid seems to drag in the second half, feeling longer than its 92-minutes.
Most likely, Wimpy Kid fans will embrace the gross jokes. The rest of us can hope the inevitable next film is better. As if.
The ratio of giggles to groans runs about 50/50.
