I don't know if anyone remembers the Ruby Spears Superman, it was one of two DC cartoon between Super Friends and Batman the Animated Series, released in 1988. Here is a review of it:

It's an interesting, it's like a combo of Post Crisis Superman, the Silver Age and the Reeves movies. It's the first animated appear of corporate Lex Luthor, but his personality seems to be based on the Gene Hackman Lex and the plots are out there.
It's not as edgy as the DCAU, but not as toothless as the Super Friends, villains can attempt to kill people in this show.
It only lasted one season, but what if lasted longer? Do you think it would have been successful if it was given another season? Would have been more remembered? Would have been swept away when Batman the Animated Series was first released? It came out 4 years before Batman the Animated Series.
