The animation is great during the middle segment in Japan in my opinion, it can definitely be smooth and quick when needed, and other moments are a bit more subdued with a slower frame rate, but it didn't bother -me-, your opinion may vary but after a few minutes I really wasn't noticing the "framerate" of the animation at all anymore, at least it wasn't bothering me because I was involved in what was happening on screen.
Overall, I think you should give it a watch if you like Predator, there's a bunch of callbacks and references to the films too.
Having watched it, I find the "strong woman" complaint really funny because goddamn there's almost nothing feminine about this character at all, except she happens to be female... , she's not pretty or young, she's a merciless relentless badass from start to finish, and doesn't feel at all like a Mary Sue that are usually seen in girlboss stuff.
Also, it's an actual feature-length film with chapters, it's not really an anthology where you can skip episodes in my opinion.
