I rewatched the old ones recently (and am currently watching the animated series from the 90s) and I honestly thought that the third one was the best.

The first one took itself much too serious, tried to be super artsy and fell flat on its face. With the third one they at least dared to play around and have a little fun. That made all its shortcomings feel not so bad.

But damn, the animated series is a blast. The first season isn’t that great but by the second season they had found their grove. The episodes where Superman meets Batman for the first time and one where he tries to save a man from a death sentence by doing detective work are especially good.
