Other reviews said: "No plot, no antagonist, no character development."
Some genres don't need anything of that sort though.
All that's also true for a lot of male-targeted harem ecchi isekai out there. If we can enjoy a slow life show with mindless feasts of big anime tiddies, op mc, story and enemies that just serve as fodder "for the PLOT", why shouldn't girls get the corresponding gender-swapped equivalent too?
If anything, the gender reversal vs other typical shows that at least I personally see for the first time makes it interesting enough to score a 6. Probably more if I were a girl ;)
On that topic, should MAL have a tag for that? "Ikemensekai"? Or is "shoujo"+"harem"+"isekai" basically the same thing? Actually, it's not tagged with any of these either... MAL, get a grip!
