Forewarnings first, this review will be quite racuous owing to the nature of this show.
Ishuzoku Reviewers is a badass totally unabashed anime of culture that sticks to its surprisingly well thought out sex centric fantasy world to explore a highly taboo subject with conviction. Its also pretty damn well drawn and looks better than most hentai/ecchi I've seen.
Every fetish, both fantasy eroge and irl such as toys, group play, pornos, lesbian, roleplay, even snuff and my personal favorite: tomboys is covered. Thankfully there is no NTR, bless the absolutely cultured creators of this anime. The fantasy ones get pretty hilariously creative with a literal skeleton worker, fairies having 'size' restrictions, a nod to bad porn acting, elves being considered ugly grannies, the true anime classic that is genderbender shennigans, succubi turning every month into destroy dick December, titty barbecues on a fire girl and birds being very lewd! Meidri has my respect for being the tsukkomi and being unlewded (sorta) to the very end though.
Not only that, some very relevant discourse is explored with regards to sexuality. Some of these are:
-buildable golems as an analogue of our own impending revolution of realistic sex androids and further implications for the abuse of others likenesses
-the total buzzkill that is stds and pregnancy irl and how convenient it is to fantasize away these very real stoppances to fornicating all day long
-Crim our lovable hermaphodite is the token lgbt character and explores this with far more tact than any reactionary sjw project from the west
-a mage making disposable magical clones you can do absolutely ANYTHING to. Some people have sick fetishes.
This well thought out execution permeates the anime in small details too with its attention to its fantasy setting, building up things like an entire egg laying culture, cyclops fetishes for eyes, demon contracts, monopolising the titular reviewers brand into a franchise and last but not least, communism!
There is no damn way a show would be able to pack this nuanced human and emotional touch like this in any form other than the anime medium; with such a topic otherwise being relegated to clinical, science focused sex docus for the sanctity of the publics moral code and sense of what's in good taste. Truly a perfect anime to embrace all our sexuality with and have a good laugh over it. And besides, as a retro anime guy, I damn approve of seeing bare titties in a sorta mainstream anime release again, after seeing the trend of actual nudity being imprisoned behind ecchi and hentai shows for so long.
