Maybe I’m a bit biased because my favorite adaptation are the Fleischer/Famous cartoons, which are IMHO definitive masterpieces. But for more well rounded, there’s the animated series which is probably the best Supes adaptation ever done. That’s usually what I go back to because again as usual Bruce Timm and co. know these characters inside and out. (Can it be a rule that Lois always jokingly call Clark Smallville? I absolutely love that.)
It certainly helps that the DCAU Superman was largely based off of the post-Crisis Superman. Why can’t that Superman appear in a live-action movie?
