Hey, I had a random though the other day. I was thinking about when I was going to re-watch all of my beloved sci-fi-operas. The problem is that I have never (!!) re-watched anything before - except random Mythbusters and The Simpsons episodes on tv. My main concern is that I would re-watch too early, thus ruining what could be an even greater experience. So I'm asking you who have re-watched before, if there is a general guideline you are using to determine when the time is right? Or you maybe have this awesome equation which involves the time since last watch (t), series length (l) and series greatness (g)? Many thanks for replies. Hopefully a general pattern will emerge that can be followed.
