Parents need to know that, like 2014's The Lego Movie, The Lego Batman Movie is clever, creative, and funny, with nonstop action. It's a little darker/edgier than its predecessor -- there are tons of bad guys, battles, explosions, bombs, weapons, destruction, and general mayhem. But because it's all made out of Legos, there's zero gore, and very little is permanently damaged (lots of things are put back together in a literal snap). Still, the main characters are constantly in peril, which could upset some younger/more sensitive kids, and one key character momentarily seems headed for a more serious end. Words like "butt," "loser," and "sucks" are used, and there's a little flirting, plus humor related to Dick/Robin's preference to go without pants when wearing his costume -- but nothing gets too risque. Batman is forced to give himself a pretty hard look over the course of the movie, eventually realizing that he can't do everything by himself and that working with a team/having a family is more fun and fulfilling than going it alone (no matter how awesome your pecs are). As with all Lego movies, shows, and games, it also serves as a feature-length toy ad -- but you may not care, you'll be laughing so hard.
