Ignore all the 1 star reviews. Its just conservatives getting mad.
Barbie is not a perfect movie. However, that doesn't mean its bad. Its a very energetic movie, but dont go into it expecting an experience only for the children. Everyone can enjoy this movie. Oppenheimer is definitely the better choice. If your seeing both, your sure to have a blast, but if you're only seeing one, i would recommend Oppenheimer.
