day is perfect for this movie" No... No, he's not. Doomsday is the BANE (pun intended) of Superman's existence... Now I'm aware that there are other, much stronger villains, but Doomsday is the physical arch nemesis to the Man of Steel. He's the DEATH OF SUPERMAN. If Zack Snyder and Chris Terrio wanted to intrigue us, they could perhaps reanimate the remains of the genetically engineered kryptonian clone (Bizarro) assumed to be destroyed by the end of BvS and use that DNA for Doomsday in a later sequel. So, in so many words: BIZZARO is perfect for THIS movie.
