- Network to the Rescue: Right Stuf rescued the anime for its Critical Mass label in September 2020.
- No Export for You: With the September 2020 announcement by Right Stuf, it's safe to say that Interspecies Reviewers is irretrievably blocked in Latin America and Nordics, as Right Stuf is only available in North America and those aforementioned regions will not have a legal option to watch it.
- Screwed by the Network:
- What happened when Funimation dropped the series for being Too Hot for TV in the U.S., Canada, UK, Ireland, Australia, New Zealand, Nordics and Latin America. The other large international distributor, Amazon, later followed suit, and so did Japanese TV stations Tokyo MX and Sun TV by removing the series from their broadcasting schedule. Luckily, Right Stuf rescued the license in North America and announced a Blu-ray release for 2021.
- The censored version of the sub was legally available to watch in Australia and New Zealand via Madman's AnimeLab service until June 2021 when AnimeLab began the process of rebranding as Funimation.
- Sleeper Hit: Early released episodes ranked very high up on r/anime's weekly karma and episode poll rankings as well as MyAnimeList's Top Airing Anime chart, to the point of going toe-to-toe with heavyweights like Black Clover, A Certain Scientific Railgun T and My Hero Academia, at least for a time. The series' profile skyrocketed when Funimation dropped it, resulting in many tuning in to the series and scoring it highly due to claims of "censorship". This undeniably resulted in inflation of its user ratings, as for a short time it was one of the highest rated anime of all time on MyAnimeList, alongside stalwarts like Fullmetal Alchemist: Brotherhood, Steins;Gate, and Hunter × Hunter, but plummeted in the following weeks as controversy died down. It's still scored highly among 2020 Winter Anime, though with the context that most agree it's a relatively slow anime season, particularly compared to the preceding Summer and Fall 2019.
- Streisand Effect: Various distributors and networks' dropping of the series due to it being Too Hot for TV led people to look for it elsewhere to see what the fuss was all about, and its popularity increased as a result.
- What Could Have Been:
- In one of Amahara's earliest prototypes for the manga, there was an entirely different angel in the Reviewers from Crim, with a much more cruel personality, and there was a cat beastman instead of Brooz. This other angel's appearance is reused in the manga proper in chapter 28, where they confront Crim out of jealousy and a desire to break their own halo and enjoy the mortal pleasures of the flesh. Four of the girls considered for reviews but as of volume 4 not used for the final release are the Amazon, the Dullahan, the Kitsune, and the Bug Queen, while the running gag about how magical races see 500-year-old elf women versus how humans like them is shown to be one of the foundational jokes for the series, as it is continually referenced in chapters 1, 6, 7, and 31.
- In this concept sketch for the series by Amahara, the groundwork for the Transportation Guild centaurs and Aloe is laid down, and a Western-style ghost girl is seen instead of the kimono-clad Spirette. Aloe's prototype artwork had her with a Bubble Pipe instead of her classy kiseru pipe.
