Parents need to know that Trolls is a cute, colorful adventure inspired by the tall-haired troll dolls that first became popular in the 1960s. It centers on peppy troll Princess Poppy (voiced by Anna Kendrick), who teams up with grumpy pessimist Branch (Justin Timberlake) to rescue her friends from the troll-hungry Bergens. Along the way everyone learns lessons about inner happiness, never giving up, and being proud of who you are. Everything has a fuzzy, felted look to it, which softens some of the danger and peril. But little kids are still likely to be scared by the greedy, hungry Bergens. And they may well hide their eyes when Poppy and her friends flee from danger and have several narrow escapes. There's also a sad moment when Branch remembers losing someone he loved. Two of the Bergens flirt, striking some "sexy" poses and exchanging a couple of mild innuendoes. Bodily function humor includes the projectile-glitter farts of Poppy's sparkly friend, Guy Diamond, whose glittery buttocks are also visible. Expect a few uses of "OMG"/"oh my gah" (the ending of the word is left undefined) and "stupid"/other insults. But in the end, what you'll remember are the great songs, the strong themes of friendship and empathy, and the fun characters.
