I'll start:
Demon slayer
TOBEVERYHONEST a silent voice and I want to eat your pancreas stories could be written by ChatGPT today.
I just never saw the point, you know the writer is building up for a moment where you are gonna cry and that's it.
The acting, music, animation quality is what makes these movies good so still recommend to watch them.
If you want to build up to something that makes you cry, do it like Violet Evergarden ep 11. Looked like an avg until the last part comes in. Which makes it a masterpiece.
Naruto Shippuden was by far the worst popularity to quality ratio I watched. Naruto is like a 6/10 at best, but that's still solid. Shippuden was so bad I hate watched Boruto (mind you, I haven't watched anime since 2021), and even that shitty reboot had more positive qualities than the most overrated delivery of media known to man. I did think Sasuke vs Itachi + Pain vs Jirahya was the best section of episodes in the series, but the downhill after that mini-arc was absolutely unmatched. It's a 1/10 show just unironically.
Reincarnated as a Slime gives me the heebie jeebies
One Piece puts my brain on the verge of contracting an aneurysm
Rising of the Shield Hero was okay for first few episodes but everything else is garbage
My Hero Academia could've been good but the characters are as deep as 50mL beakers and there is nothing interesting about it.
Naruto is trash
BOFURI seemed like a wholesome anime I could just watch to pass time but every minute i watched would kill a brain cell or two
And many more but I couldn't be bothered
