Re: What villains are left for a 4th film?
I believe they said it was only going to be a partial re-boot, were non of the human characters come back, but the TF's themselves will be the same, so I think it will continue the story in some ways.
2016 movie ratings out of 10:
1)Captain America: Civil War-9.5(2)Deadpool-9(3)X-Men: Apocalypse-8.5(4)The
Revenant-8.5(5)Batman v Superman: DOJ-7.5
