The animators go very fast. And they don't repeat instructions for those who cannot keep up. My best piece of advice would be, can your kids keep SILENT for the duration? When anyone in that class says anything, it means others miss key steps of the instructions. One year, we had a dunce take a cell phone call and it made hearing the instructions virtually impossible.
If your kids can be silent, go ahead and enjoy. If they are the sort to ask you, "What did he say?" or "I can't hear him," etc., then please stay away until they can stay quiet. You know the sort I am talking about.....the questioners......the ones who make movies unbearable because they pepper their parents with questions throughout the movie and the parents don't have the sense to tell them to be quiet or remove them. If your kids can be quiet during a movie, church, a wedding, etc., then they are good candidates.
