Re: For how long will the MCU go?
It is contingent on the success of the films; from the perspective as a fan and screenwriter, rebooting is unfathomable at this point. If anything, the MCU has just gotten started, and they have pierced only the top of the proverbial iceberg, in terms of arcs and storytelling.
Justice League (TBD)
Batman: Ben Affleck. Superman: Henry Cavill. Wonder Woman: Gal Gadot. Green Lantern: Tom Anderson.Darkseid: Michael Cera.
Aquaman: Alexander Skarsgard. Martian Manhunter: Liam Neeson. The Flash: Neil Patrick Harris.
