The science behind the movie was very clever. What has disappointed me is that Disney/Pixar keep on pushing the sexism gambit in their movies. This movie wasn't as bad as some of their others, but they are Consistently failing to address gender in a balanced way. Does anyone male in this movie do/say anything good? What about Frozen? The stupid (Wessleton) and nasty (Hans) are only male. Brave? Same thread. The kings/Princes are all obnoxious and/or stupid. Wreck-it-Ralph : Kowalski strikes Ralph across the face as a show of might and it's meant to be funny (ie. The modern assertive woman who bashes men as "humour") Several of the tinkerbell movies where ratchet & clank are the typical stupid males (and in most of them, they are almost the only males). To be fair. They do portray the southern belle as a dimwitted hick too, which is the stupid southerner prejudice emanating from the U.S. civil war. However, they did a great job with Tangled and Princess and the frog - there's a much better gender balance in those movies. It's a shame. You take your kids to see a supposedly family friendly movie and you cringe at the sexism that is pushed by the writers and directors. Do you just shrug it off, wondering if this prejudice won't rub off on your kids - or do you highlight the sexism to your kids and ask how a large studio could be so consistent in their bias, despite their deep attention to the science. I can't help feel there is more sexism and more conscious sexism than there has ever been. It really makes me sad.
