@Bar-El had made a thread talking about it here:
…but it’s my favorite version of Superman ever put to screen, so the more the merrier 
This series highlights how great Superman rogues can be, if given the time to shine. Metallo is almost tragic, Parasite is a lowlife, Toyman is creepy, Darkseid is pure evil, etc.
I made a thread discussing where I think they go wrong with Toyman- this show showed him to be unhinged, so his motivation was less ‘I lost my business and I’m upset about it’ and more ‘I lost my childhood and my mind, and I’m gonna make the world pay for that’.
I love that Livewire was a shock jock who had it out for Superman, turning a whole crowd of her supporters against him. That type of villain resonates today more than ever.
Like you said, the voices were iconic. Dana Delaney as Lois is who I hear when I read her as well. Clancy Brown as Lex, Corey Burton as Brainiac, Michael Ironside as Darkseid, etc. They’re all just so good in their roles…the episodes never get old.
