An anime episode has just achieved something that no television series, from any country, of any kind, had achieved in nine years: a perfect rating of 10/10 in IMDb. Responsible is episode 11 of the fourth season of Re:Zero − Starting life in another World, that with more than 12,000 votes It became the highest rated episode in Amazon’s platform history.

What is the best-rated anime episode on IMDB?
Episode 11 of the fourth season of Re:Zero currently holds that brand, with a perfect rating of 10/10 over more than 12,000 votes registered in IMDb. It is, to date, the highest data ever achieved by an episode of a television series on the platform, surpassing any production of any genre or country of origin.
Three records in a single episode

That result breaks three simultaneous barriers: it is the episode of any television series with the highest rating ever recorded in IMDb; It is the first time that an anime Isekai based on a light novel achieves this historical mark; And it is the first perfect 10/10 rating that the platform registers in nine years.
Why is it so difficult to achieve a 10/10 with thousands of votes?
The more votes a degree in IMDb gets, the more difficult it is to maintain a perfect rating: it is enough for a fraction of users to qualify lower for the average to fall. A 10/10 consensus with more than 12,000 votes is statistically extraordinary, making this episode a case study within the community that closely follows anime and global television ratings.

Why does it matter that it is an Isekai anime?
The Isekai, stories where the protagonist is transported to another world, is one of the most saturated genres of current anime, often criticized for its repetitive formula. What Re:Zero, one of the founding series of the genre, achieves this result works almost as a claim: it shows that the Isekai, well executed, can reach the level of any prestigious television production.
The pattern of extreme qualifications in IMDB usually coincides with moments of narrative climax. For a franchise known for its handling of the psychological suffering of its characters, an episode capable of generating this consensus suggests that Season 4 is running one of the most important arcs of the entire series.
