Most of the giants don't wear much clothing.

Sophie is shown very briefly topless. Since she is a little girl, she has no bare breasts showing.

In the boy's dream sequence, he is shown naked and part of his crotch is shown, but his genitals are not.

No blood or gore, but there is some occasional aggressive violence from the bad giants.

No swearing (because it is for family audiences), but some very mild comical name calling!

There are scenes that show giants who are very monstrous in appearance and demeanour.
