Common Sense Note
Parents need to know that Jack and the Giant Slayer is a big-budget adaptation of the classic English fairy tale. It's full of swashbuckling action, computer-generated fantasy violence, and considerable collateral damage. The violence is the result of the vengeful giants holding an (understandable) grudge against the humans. People die from being eaten (the giants tear people apart to eat them) or burned, plunging to their deaths, getting crushed, and other catastrophes. There are also sword fights, and a well-liked character meets a particularly gruesome end. There's mild romance between Jack and Princess Isabelle (they flirt and share a couple of sweet, chaste kisses) and a little bit of language ("hell," "bastared," etc.). In classic fairy tale tradition, the hero is brave and selfless, and the heroine -- while definitely up for adventure -- finds herself in need of saving on more than one occasion.
Sexual
Content
Lingering looks lead to hand holding, embraces, and two kisses.
Violence
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.
Language
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).
Social
Behavior
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.
