As is generally the case in fantasy adventures, selflessness is rewarded, and a couple is allowed to marry for love instead of status. The dangers of power in the hands of the corrupt is made clear.
Positive Role Models & Representations
There's a significant body count and plenty of fantasy violence. People die plunging to their deaths, being eaten/trampled/burned alive by the giants, or squashed when the enormous beanstalk falls back on the kingdom. The king's guardians (and Jack) kill giants as well, usually with a knife or sword, but also with flaming arrows. One well-liked character is killed in a gruesome way. The giants tear the humans apart to eat them.
Lingering looks lead to hand holding, embraces, and two kisses.
Very infrequent use of "hell" and "piss off," plus some mild insults like "stupid" and "idiot" and one interrupted "F--" exclamation. Also some scatological humor (the giants burp, fart, and pick/eat their boogers).
