Ishuzoku Reviewers is gleefully and unabashedly positive. Yes, sex-positive... but also just positive overall. Don't expect deep social commentary on sex trafficking and other real life issues that prostitutes encounter. These things are worth talking about... but it's also worth having a simple celebration of life, sex, and the existence of brothels. You too will be drawn by the festive atmosphere and you too will enjoy the diversity of life together with the characters - be it the reviewers or the prostitutes. And, frankly, what more can you want?
That's it. If this is your first encounter of the franchise, that's all you need to know. Go watch it. But, of course, if you've read the manga already, you're wondering why this **** is wasting your time with obvious truths. So, let's say a few words for you too:
While animation is not outstanding, it ain't bad either. It does what it needs to do, translating well the feel of the manga art to moving pictures. Sound design is also in the same category, though the opening and the ending themes must be specifically applauded as great songs that capture the feel of Ishuzoku perfectly. Whatever budget was saved from the animation obviously went into the cast instead. There isn't even one weak performance, with some pretty big names throughout.
But, as far as the process of adaptation goes, the strongest parts are the scriptwriting and the directing. The choice of what to adapt, the timing and pacing of the adaptation, and the way that the adapted manga chapters are EXTENDED with additional (sometimes even lewder) content - these speak volumes of the love with which this anime is created. In fact, this exact effort to round up the chapters' content is what makes the Ishuzoku Reviewers anime a must-see for the manga readers too.
