Yes female action heroes are a trope now. They've over-played it, but of course anything from Marvel or DC is going to be shit. These days they're just movie mills pumping out the same old rehash.
The Alien movies made a female action hero seem natural. They did it right. There's been a few others that have done it right. More have done it wrong.
I don't know anything about the Barbie move since I haven't seen it. I would like to see it but will wait until it comes to streaming. My wife saw it with a group of her friends and said it was cute and weird, but definitely worth the watch. So evidently it's not in the same caliber as Legally Blonde.
Also why the seemingly arbitrary graduations, 24 hours, 60 minutes, 60 seconds. If it was say 10 hours in a day, 100 minutes in an hour, 100 seconds in a minute, seconds would be close to the same amount of time. Same with latitude and longitude, why 360 degrees in a circle with 60 minutes in a degree and 60 seconds in a minute.
