I've watched numerous anime, and many of them are rated 10. However, until now, I never felt the urge to write a review because even those rated 10 had something that bothered me too much.
And it's precisely the absence of that feeling that compelled me to write about Frieren here on MAL. First of all, if you haven't watched it yet, they released 3 episodes on the first day of its premiere, and these were quite important.
Frieren's pace is slow and spaced out, be aware of that. When I started watching, I knew nothing about it—no trailers, manga, reviews, etc. I only knew it was about an elf. So, watching the initial episodes, the way they unfold gives the impression that there won't be any actual battles or action.
But that's the author's storytelling style, and it makes sense. She's an elf who has lived for millennia. Why would she hurry? Anyway, I highly recommend you watch it if you enjoy high medieval fantasy.
The only criticism I will make here is the lack of a more striking soundtrack.I'm not saying the soundtrack is bad, but it's not like Naruto and Nanatsu no Taizai, which, for me at least, are the best anime soundtracks I've ever watched.
