Diary of a Wimpy Kid: Rodrick Rules takes our intrepid wimpy hero through seventh grade - more struggles to be "popular", more efforts to make his unaffected, unpretentious and childish pal Rowley less of an embarrassment.
It makes more of an effort to connect the big screen film with the Jeff Kinney books - lots more animation in the Kinney stick-figure style.
It just takes a very long time to get going.
Apparently seventh grade doesn't pack as much potential for amusing, scarred-for-life trauma as sixth grade.
The problems of Greg Heffley (Zachary Gordon) lie much closer to home, this time around.
His baby brother Manny is old enough to talk and old enough to rat him out.
And older brother Rodrick (Devon Bostick) has become "the king of laziness, except when it comes to torturing me".
Thus, Greg's academic career is hampered by teachers who tar him with the same brush as his underachieving sibling.
Greg's crush on the willowy new blonde model-classmate, Holly Hills (Peyton List), is doomed by Rodrick's pranks at the skating rink and at church.
Thankfully, mum (Rachael Harris) has noticed the boys aren't getting along.
A delusional self-help newspaper columnist, she concocts a scheme to pay them to get along.
"Having a brother's one of the most important relationships of your life," she lectures.
Rodrick manipulates this do-goodiness into a way to pay for gas for his van while he continues to trick and torment Greg and steal mum's eyeliner so he can look the part of a rock drummer in his band, Loded Diper.
The sibling rivalry doesn't have much to offer until late in the film, when Rodrick starts passing on his "rules" for getting by to the wimpy kid: "Don't be good at something you don't want to do" - say, washing dad's car.
"Always lower Mum and Dad's expectations."
Another mum trick, forcing the boys to spend the weekend with their grandpa in a retirement home, leads to a funny chase-in-his-underwear memory for Greg.
But, as in the first Wimpy Kid, school holds more promise for comedy as Greg creates a cruel "nobody sees you" game for his classmate Chirag (Karan Brar, hitting the affected Indian accent too hard).
There are weak gags involving the gross classmate Fregley, and goofball Rowley (Robert Capron) inadvertently teaches Greg how to lip-sync to Ke$ha and to be himself, not try so hard to fit in.
As kids' entertainment, Rodrick Rules is harmless enough.
But it's less broad than the first film and less funny.
Animator-turned-director David Bowers has little to work with in this script and once again no money to spend on funnier actors in supporting roles.
Steve Zahn, playing the dad who is wise to the ways of sneaky throw-a-party-while-the-parents-are-away boys, manages a laugh here and there, as does Harris as the smothering-hovering mother.
But there are no funny teachers, and most of the Westmore Middle School classmates seem to have aged out of their amusing years.
Without more giggles, this Wimpy sequel simply wimps out.
Diary Of A Wimpy Kid: Rodrick Rules is currently screening in theatres.
