Superman: The Animated Series made him very interesting and may be the best existing Superman media.

By himself? Not particularly short of a handful of stories that play well to his character and dynamic, and most of those need a lot of prior buildup that the DCEU doesn't have time to do.

He works best as a foil to a different hero, and in that way he is easily slotted in to grant conflict or resolution to their stories without a need for a genuine threat.

But Hollywood writers can't handle that, so instead its "le subverting expectations" all over again to make him weak and sad.
