You’ll never know how good the first three “Diary of a Wimpy Kid” movies were until you’re forced to see the fourth one. And I say this as someone who has seen all the movies — and read all the books — with my 7-year-old son. We’re both fans of the series. But this shrill reboot with an all-new cast never comes close to capturing author Jeff Kinney’s combination of humor and insight. My one-star RogerEbert.com review.
