This movie is pretty good, however, if you are a girl that is younger than 10 years old, I wouldn't watch it during that age because it's about a female's puberty at the ages of preteen to young adult.
SPOILER ALERT!
This movie is exactly about this 13 year old girl named Mei (full name : Meilin Lee) that had a family that all female members turned into a red panda (including Mei) during their puberty ages and each one of them must learn how to fix by resisting all the things they like. And Mei and her friends tried to help Mei to fix her red panda by trying to make her resist the things Mei likes, like kittens. However, one day Mei saw her favorite idol singer group coming to her town for a concert (which made her feel very wanting to go to the concert), but her mother wouldn't let her go. So while Ming (Mei's mom) tried her best to keep an eye on her daughter, she had no idea that Mei and Mei's friends are having a secret gathering to go to the concert, but one day when Mei was at a concert without letting her mom and family know Ming looked under her daughter's bed and figured out that Mei was trying to go to the concert. So when the concert day finally came, Mei and Ming got in a huge fight (and of course Ming wasn't abled to stop Mei), but during the fight, right before Mei went out, she accidentally broke her mother's necklace which contained the power to protect Ming from turning into a red panda, so Ming obviously turned into the panda and went finding her daughter while she was having fun with her friends. And when Ming arrived to the concert arena with her big red panda form, and when she found Mei in the audience, she got really furious, but with the help of Mei's family and friends, she was able to defeat and help her mother from her red panda form.
