Between Superman: TAS, Batman: TAS, Batman Beyond, Young Justice, JLA/JLU, Green Lantern.... they really know how to put great storytelling into a compact 22 minutes. The movies, having huge budgets, A-List actors, SFX, and 2+ hours to tell the story, just blow it time and again.
Just re-watched a great Superman TAS crossover episode with Batman TAS. Superman/Robin team up. Love it!
