Despite my resentments, I still try to assess the situation sensibly and accept it as it is.
Horror (including slashers and Italian giallo) is a fairly marginal side of art. This genre will never be liked by everyone and should not be liked by everyone.
Another thing is that Resident Evil in 1996 was conceived as such a game, but over time the series mutated into a tokusatsu show, that is, in the superhero genre of the Japanese format. If before we could see the violent and bloody deaths of characters, disemboweled corpses and disgusting rotten zombies that got wet in the baths (even Jill once could not contain the urge to vomit), over time, the series abandoned the high degree of violence altogether. If before the characters just wanted to survive, now they began to save the world. If before the characters challenged the huge corporate machine and fought against a corrupt system, now they are fighting with specific supervillains who want to take over the world, and all viruses and corporations have gone into the background so that they have become exclusively points of support for the plans of these villains.
I even noticed that a lot of people who are interested in the Resident Evil series today do not consider it horror. Such fans are not interested in horror movies at all, but they are interested in anime and comics about superheroes. This is not a reproach at all, but just my personal observation.
So, in fact, it should not have been surprising that when the series returned to the horror culture trail, many did not appreciate it.
