ok so that's a stupidly long article so i skimmed it, but basically it comes down to
1. the women should have been stronger (that would be cool! here, let me show you my idea for elsa fighting people with magic powers in frozen 2)
2. there should have been more women (eh, i guess that would be good? but i don't see the problem because there's only four main characters (anna, elsa, hans, kristoff) and 50% were female)
3. anna's stupid (i fully agree with this one)
4. elsa's stupid (wellllllll......... kiiiinda but she has the excuses of 1. actually being dangerous and trying to protect others when she runs away and 2. being isolated for her entire life so she doesn't really understand the consequences of her actions very well)
i think the rest of the article is just them complaining about minor things. the real reason they're mad is because they were hoping they'd see a movie where there were super-strong female characters, and this wasn't it. i kinda agree with them there, but i guess i've kinda become used to not seeing any strong female characters (can someone please make a WWII movie about the Eastern Front where we see awesome female Russian snipers or something? that'd be awesome)
so... yeah. it looks to me more like they were unhappy with the females in the movie and decided that was the only thing important in movies and so they didn't like it. i guess they're really more mad about how everyone's obsessing over it being a huge feminist movie when it isn't, and i can agree with that too
still kinda silly to hate the entire movie because of that, though. feminism isn't the only thing important in movies
