At the time of writing, IMDB has only 3 reviews: 2 are 10/10 praising everything, and 1 is 1/10 with complains based mostly on the perceived show's agenda. I would say the latter is a bit more honest, although main character being a lesbian woman of color is definitely not something that detracts anything from this show. I would even say, that inclusivity in this scope was done right: it's simply neither here, nor their, which is the whole point of inclusivity, in my opinion.
The show has quite a few problems, that may not necessarily be because of the agenda, although I do see, why it may feel that that's the root cause. For example, that 1/10 review complained about white men being shown as villains. That is somewhat true: in the 1st episode we see, I think, 4 men, if counting those with lines, and 2 of them are definitely villains, with a goal to conquer. But you need to keep in mind, that they are from times and places, where this was kind of normal, especially, when talking about the Roman guy. Roman Empire would not be as big as it got to be, if there were no people like that.
The problem with these characters is that they are... Flat. It does not look like they have anything to them besides desire to conquer and dominate, and the desire is there just because, and not because of some deep reason. In fact, the Roman guy is also shown relatively stupid (albeit not a complete idiot), which kind of contradicts an image of an actual Roman conqueror. Those were smart, arguably had more smarts than brawn, often time resorting to politics rather than actual war, despite what Hollywood wants us to believe.
There was also a kid, which did not mean much, and a soldier from 1944. The soldier seemed to be the most interesting character, to be honest, because he was shown first as somewhat rude, but then also not as avert to kindness, too. I mean, he did try to help the girl, too, although did not get a chance to do that properly, partially to the fault of that girl.
That's where I do agree, that modern agenda may be taking over a bit. Not because strong female leads are bad, no, because this particular character just does not make sense. She tried to off herself, before she appeared on the island. She had no idea, what happened, where she was, what were the rules of this new world... Nothing. She sees a human, and the first thing she does is give him attitude towards his joke (or probably half-joke).
But maybe this was first reaction, due to stress? No, not really. She was giving attitude to everyone. Instead of being weary of people riding dinosaurs and shooting arrows, she behaved... Almost cocky. And she even tried to "poison" her captor right away, in order to run away, because... She likes dinosaurs.
Like, really, that's her main characteristic. The main thing, that in the end makes her say "I will survive", even though she intentionally took too many pills before this. I was a fan of dinosaurs when I was a kid, and I would be fascinated to see them up-close, but in her situation, I (and probably most humans) would first think of how to survive. And not try to domesticate creatures around me. Which, by the way, is not how things work. A wounded animal will not bond on you just because you pulled out an arrow out of its side. It will definitely not run back to you, while you're in a place with dangerous predators.
It's not just unrealistic behavior of both humans and animals, that makes this show mostly bad. It's pacing is all over the place: it started really fast, but then it slowed down to almost a crawl, and then suddenly became fast again, when it was a great time to give some more exposition. I guess creators wanted it to feel "edgy". Animation is also inconsistent in quality, relying heavily on blur in certain shots.
The storytelling is bad, too. It relies heavily on flashbacks, which are thrown into us in small chunks every few minutes of the episode. It would have made way more sense to show all those flashbacks in the beginning of the episode, all in one chunk, and then start the island story-arc. Something that's been proven to work time and time again with lots of isekai stories. This could have allowed for proper pacing, too.
In the end, I do not recommend this to anyone, really. Unless, maybe you want something running in the background, or you find main character so hot, you just can't resist. I get that, but for me it's not enough. I have lots of other stuff to check out.
