I'll start:

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.
