Despite his ongoing attempts to become popular with his peers (each and every one of which backfires), Greg learns important lessons about being himself and sacrificing his self-respect for someone else's best interests -- in this case, his older brother, Rodrick. The siblings find a way to bond with each other this time around ... although their bond springs from their mutual need to cover up some bad behavior.

Some bullying and threatening. Rodrick picks on Greg mercilessly, and in one scene, they physically start to brawl; Greg jumps on Rodrick, and they both fall to the floor, struggling.

Some minor flirting, as Greg develops a crush on the pretty new girl in school.

Frequently used insults include "jerk," "lame," "loser," "fart," "doofus" and "butt brain." Also "oh my God."

The kids in this movie seem to eat a lot of junk food, but for the most part, brands are effectively disguised or parodied. A bottle of "Cola" is visible in one scene, and it looks like it might be "Coca-Cola," but it's not for certain. "Cheese Curls" are visible, and a "Twix" candy bar is seen more than once.

Rodrick throws a wild party, and teens are seen drinking from red cups, the contents of which are unknown. No mention or suggestion of alcohol is ever made, but in that context, some viewers could infer that that's what's in the cups. In one scene, Rowley lip-syncs to Ke$ha's "Tik Tok," which includes lyrics about drinking and partying.
