Characters make lots of iffy decisions (including lying and deceiving each other) and treat each other poorly; although there are apologies at the end, it seems a bit too little, too late for what transpired. But Peter and Thomas do find a way to get along in the end and work together for Bea's sake, and characters do talk about the fact that love isn't a finite thing: There's enough to go around for everyone. Peter also learns to listen to others ... sometimes. Jokes about Mr. McGregor dying of "bad lifestyle choices" (i.e., drinking and lots of junk food) and a few fat jokes at the expense of Benjamin bunny and a pig character -- but the movie does make eating vegetables look like fun.
Peter and his sisters have lost both of their parents; their dad for sure was eaten in a pie by Old Mr. McGregor (there's a flashback to the sadness that caused). Old Mr. McGregor dies unexpectedly of a heart attack; Peter pokes his open eye to check. Several perilous situations (rabbits are caught by humans more than once), plus dynamite, explosions, and dangerous pranks; animals attack a human with blackberries after discovering he's allergic to them (he has a reaction and must treat himself with an EpiPen). Humans chase rabbits, threaten them with rakes, etc. One supporting character briefly seems to be dead (she's not). Threats of rabbit-eating. Lots of chasing and falling. Human characters are shocked repeatedly by electricity and snapped in rat traps. Joke about broken ribs. Temper tantrums that include destruction of property.
Two human characters fall in love. Dating/flirting scenes, kissing. Nonsexual, but part of Old Mr. McGregor's bottom is shown (Peter tries to insert a carrot into the exposed crack). Joke about how Peter doesn't wear pants. Peter briefly flirts with a "cute" girl bunny. A rooster talks about having "fertilized all those eggs" and tries to become a responsible father to many baby chicks. Visual joke about Peter's face appearing in the crotch opening of a pair of jeans. Joke about the meaning of the word "homewrecker." A fox goes "streaking." A joke about a jacket includes a reference to nipples. Thomas is shown in his boxers.
Insult/crude words include "halfwit," "imbecile," "idiot," "stupid," "butt," "heck," and "country bumpkin."
Connected to lots of offline Peter Rabbit merchandise. Thomas works at the famous British department store Harrods and drives a Land Rover.
Drinking, Drugs & Smoking
During the animals' rowdy house party, it's implied that one character is high. In a montage of Old Mr. McGregor's poor lifestyle choices, he's shown drinking. Running joke in which, whenever anyone talks about someone who has died, characters squeeze berries and let the juice run to the ground -- a reference to gang members pouring beer on the ground to memorialize dead friends.
