Torisunanohokori said: Correct me if I'm wrong, but that list kinda just seems to be what aired during that time period. I've always thought that, to be a real classic, an anime has to still be known today.
If that is the case then most of the shows that are before your time are not classics.
People like Babe Ruth, And Dave Armstrong wouldn't be classic, unless you know who they are.
Athletes are not necessarily held to the same standards as anime. But Babe Ruth's name is well known today, baseball legend that he is. But do you remember the names of all of his teammates? His managers? His opponents? Bet most sportscasters today don't even know that.
I feel a classic has to be memorable in some meaningful sense when it is defined as such in order for the term to carry any meaning beyond "anime made before year XXXX".
