Warner Bros. is betting big on rebuilding its DC cinematic universe – but early signs suggest uncertainty rather than momentum. This year's Superman reboot laid down the foundations for the DCU in the way many would have hoped, but next year's Supergirl is already being approached with skepticism following backlash to the first trailer. While all hope is certainly not lost and there is still plenty of potential, a very different shared universe is quietly taking shape, beginning next year with The Cat in the Hatreboot.
