I was wondering if you guys feel that constantly watching the same anime, after any given time, ruin the experience of that show? Given that you already know the plot and the characters, is watching the series again really necessary?
For me, I usually have to wait several months after I finished the first viewing before jumping back and watching it again. It seems that the less I remember of that first viewing, I can later enjoy it more the second time around as I had forgotten most of the plot.
(though I think Azumanga Daioh can be an exception because you can watch any episode at any time and it would still make you laugh! )
