Not caped suits, but law suits. The endless haggling over the copyright, the legal “ownership” of Jerry Siegel’s creation, seemed over. Several times. Especially in January.
But since nothing is EVER settled in legal land, Warners is trying to shut the door on this once and for all.
While one can certainly sympathize with a creator who never got truly rich off his greatest creation, and the example Disney has set re: copyrights extended to infinity and beyond (Nobody else’s works are treated that way), Siegel did “sell” Superman, and his heirs didn’t do a thing to earn their “share” of his legacy.
