For me, I think Infinite Stratos isn't nearly as bad as people make it out to be. It's not good, and I have my issues with it, but I've seen worse
Jujitsu kaisen.
Overlord.
Dare I say it? Dandadan.
These are too tier "meh" anime. I liked what I watch, but I'm not going out of my way to watch more. There a dozen series where I watched the whole thing, and couldn't tell you what I liked.
Series that move the anime needle for me? Frieren and Delicious in Dungeon.
