5. An After-Credits Scene
One of the most exciting parts of the Marvel movies is the fact that they shoot mid and after-credits scenes which tease a future installment in any number of their franchises. Warner Bros. failed spectacularly at this with Green Lantern’s baffling and pointless effort back in 2011, but they could rectify that here with a scene either setting up the villain for another Justice League movie or even a future solo movie for Batman or Superman. More to the point, it could be used to set up a spin-off for lesser known characters who will be introduced here, although a shadowy shot of someone like The Joker or Doomsday would have fans going positively crazy with anticipation for another installment in the Henry Cavill or Ben Affleck led film series’.
