I'm assuming by how quickly she started calling the plot an "isekai", that she's more familiar with modern anime than older classics. To think, that isekai is so common now, but the current glut of isekai series are sooooooo different from the major isekai series from 25 years ago. Back then, it was all Shoujo and the stakes were much more severe. Sure, there was Reverse Harem, like Fushigi Yuugi, and comedies like Those Who Hunt Elves. But there were so much more series like Vision of Escaflowne, Red River, From Far Away, The Twelve Kingdoms, Savior, Magic Knight Rayearth, Maze, etc. So it was funny to think of someone more familiar with those Harem, "power fantasy", modern, male protagonist wish-fulfillment isekai, suddenly watching classic Shoujo isekai. Yes, the girls who get transported to another world turn out to have/gain some magical powers, but it doesn't make them overpowered. They're going to be in danger a lot of the time. lol
And it's so funny to hear someone constantly comment on how unfazed Kagome is by everything. You don't understand. Back in those days, when female characters were constantly screeching, running, fumbling, clutzes, totally dependent on someone else to save them, they spent so much time crying and being scared. And we'd all yell at the screen or the manga page and wish they'd be more proactive. Sometimes you'd get isekai where the heroine was brave for a moment or two, but then the series would settle into her being mostly dependent on her love interest male bodyguard. Maybe she'd have a mouth on her, to show she had some guts. But for the most part: helpless. That's why the Shoujo isekai where the heroines had some combat skill or were actively learning to fight, were so refreshing. It was also why the Inuyasha manga did this better than the Inuyasha anime. Even in just these first 2 episodes, Kagome was changed from more instances of trying to pick up weapons and fight herself, to more instances of ordering people around, arguing, holding back antagonists by yelling at them. Maybe by now, resolving conflict with words instead of violence is cooler. But back then, after we had had decades of helpless "damsels in distress", you don't understand how desperate we were for heroines who could fight physically. Fantasy fiction can be more allegory, after all. Why should girls not get that metaphorical power in fantasy genre fiction? It sucks when even in fantasy fiction, the girls get limited to only words as their weapons, when they could be having "power fantasies", like the boy protagonists have always had. It's why so many Rumiko Takahashi heroines, like Kagome, were a revelation. They didn't just scream and wait for rescue (and usually for the sake of setting up a "romantic" rescue from the love interest bodyguard). Kagome and Takahashi heroines did more, were proactive, and tried to do all the smart, clever, gutsy things, that the audience keeps yelling at the screen for them to do.
