Because you won't get the anime you want.
1. You are looking for a fantasy anime with action scattered all over the place all the time.
2. You are a person who likes mystery and psychological anime.
3. You are bored with generic fantasy stories.
4. You want an epic life story journey.
I say that this anime deserves to be ranked first in 2023 and 2024 early. Not because the anime surpasses all existing anime, but because the anime provides a standard taste for the genre where most fantasy anime in this year have a bitter taste because they mix a lot of spices in it. This is like a soup that is not bad or also very expensive, this is a taste that you should be able to find in everyday life and everywhere but somehow you can't.
1. Firstly, this is not a fighting anime, where you will see the enemy hitting the main character and the main character hitting back until both of them can't take it anymore. This anime uses magic and not magic that you don't care about, the concept of magic is a normal feeling that you should imagine when fighting wizards in fantasy stories or games. This means that each attack will have a big impact but will have a short duration in a limited area. Even fighting indoors will not damage the surroundings until they leave the building. Even the impact that looks so grand will make you ask how the room came to be intact. So if you are expecting a very intense fight where they exchange attacks, forget about that. Anime ini bukan Fullmetal Alchemist series.
2. If you really like mystery, psychology and philosophy anime like Kino no Tabi, Detective Conan, and so on. Then forget to watch this anime. Unlike the genres above you won't have the structure of the world explained through Dialogue, you won't get the philosophy explained in depth. You need the glass to be half empty beforehand so you can understand. Here you yourself must be able to put together every incident, find character development, look for the causes and effects that occur. No one will explain to you all the time what happened, why it happened, what developments happened, when it happened, where it happened, and how it happened, through dialogue like Conan. If you expect to get an explanation so you understand what's going on through dialogue you'll be confused at some junctions.
3. If you hope that this anime provides an unusual perspective on the story then forget it. This is a standard story where you will see humans and Elves look like good people and Demons are evil creatures without consideration and research. You won't be able to find a story where the Demon Race turns out to be good and humans despise them. In this anime, Demons are a pure evil race and you will be presented with that reality in the anime. It's up to you to be ready to accept that reality or not. You won't get the fact that you can live side by side with Demons in Frieren's world. The world in the anime is very standard bedtime fairy tale fantasy.
4. The journey in the story is also not very deep in each episode. In general, you will continue to be faced with the main character. You won't find the development of the supporting actors very intense. You see the main character talking, remembering the past, and talking in the present based on his memories. You are almost like accompanying a grandmother (Frieren) who has have Alzheimer's. He traces his past life on his journey in the present. So each character will not get an in-depth explanation so you can love and sympathize with them. Apart from Frieren, you will only be given one or two scenes or portions that explain their background, but you won't be too attached to them. So if you are asked to study Frieren's story or that person, you are not sure about that person. Because you still want to know what happened to the main character. And when you start to become disinterested in her you don't have a supporting cast that you want to dig deeper into.
So in conclusion, if you hope to get something big because this anime is ranked 1st then you have too high expectations. You will fall too hard, therefore you lower your expectations to the level that this is a boring, ordinary fantasy anime. So when you watch it you will think "It wasn't that bad after all."
