Parents need to know that "The Lego Movie 2: The Second Part" is the sequel to 2014's hit "The Lego Movie." Like the original, it's a funny, entertaining adventure that centers on Emmet (voiced by Chris Pratt) and Lucy/Wyldstyle (Elizabeth Banks). This time around, they're defending themselves from mysterious invaders who seem bent on destroying Bricksburg – and then kidnap several of Emmet's best friends, including Lucy. So you can expect lots of action, including chases, fights, rescues, explosions, weapon use, dinosaurs, spaceship battles, and more. Since everything (and everyone) is made out of Legos, the stakes never feel too intense – but younger or more sensitive kids might be upset when sympathetic characters are in peril or argue with each other. Otherwise, content is quite mild, with a couple of uses of words like "heck" and "butt" and some flirting between characters (Batman also shows and sings about his pecs). And there are positive messages about perseverance, teamwork, friendship, cooperation, and loving people for who they are, not who you think they should be.
