what shows do you think you should see again, regardless of whether you actually will?

I haven't fucking watched Sayonara Zetsubou Sensei in 15 years and I want to see if it holds up to what I thought of it way back when.

I really should re-watch Nanoha and Nanoha A's, but I remember the first season being a bit of a slog. It's not long, so maybe I will...

also, I really want to re-watch original Gundam but it's so long lol
