Definitely take your kids, especially your girls, to see this movie.
Yes, there's violence, but there's absolutely no blood or gore associated with it. Yes, there's some romance, but it's not gratuitous. The romance teaches Diana that there is good in humanity when she was starting to have doubts. It all had a point, including the one character getting drunk (all he did was sing in a bar though). Things that could normally be seen as demerits to a movie were done so well in this one that they are outright necessary to the plot. The director been addressed issues that normally bug me, like how can people who've never encountered regular English-speakers know how to speak English? Why are the armor ensembles they wear on the skimpier side? Yes! These are actually addressed and have answers that make sense! And despite the short skirts, Diana is NEVER used as eye-candy. She is used to show strength, and that is absolutely amazing.
Now yes, I do recommend this movie for even young kids. The messages of women being strong, not only Diana, but the other Amazons, and even Etta, is one that little girls, and even us adult women, have lacked. Women in superhero movies have been created as sidekicks, support characters, love interests to be saves, or as nothing more than gender-flipped Mae characters. Diana is a hero in her very own right. Seeing her storm No Man's Land has choked up so, so many people who otherwise don't get choked up at movies. That scene really starts to drive home how we have been deprived of such a character, and makes us proud to be women, to finally see that strength very bluntly splashed across the screen. People need saving, and she's not going to hide.
This movie is a game-changer, and a life-changer. We need more Wonder Women, and more Patty Jenkenses. The genie is out of the bottle, and there's no point in trying to force it back in. We need more, and if we don't get more, we'll know what we're missing.
