Facile, too long, intermittently boring, no new or innovative ideas. A good movie for youngsters -- maybe high school kids or younger. One reviewer said "better than Oppenheimer." I had the totally opposite reaction -- all 3 hours of "Oppenheimer" were completely compelling; Barbie felt like it lasted 3 hours but it was only 2. (I checked my watch about 5 times.) "Oppenheimer" is for adults (though kids could learn something from it as well); "Barbie" is for kids. I think Greta Gerwig is very talented, and this movie seemed to be a waste of her talent. (Her husband Noah Baumbach, who was her cowriter, isn't half as talented. Maybe if she'd written this one on her own, it would've been better.) I could've skipped this one -- clever idea that didn't need 2 hours and all that hoo-ha to make its point.
