One of the many complaints and issues many had with the most recent “Batman v Superman: Dawn of Justice” trailer was that too much of the story was revealed. One common remark in relation to this, was the reveal of the iconic Superman villain Doomsday. Although the characters appearance had been speculated, nothing was confirmed until his appearance in that preview.
Speaking with The Daily Beast, director Zack Snyder stands behind that decision to reveal Doomsday in the trailer:
“We had a long conversation about just taking ownership of that, of giving it to the audience in a controlled way that I felt was consistent with the escalation of the campaign. To us it really made sense to give [Doomsday] to the audience now. I really wanted to make the audience a promise that… though I’m super excited and happy and fulfilled by the conflict of Batman and Superman, there’s also a bigger world to start to think about.”
He was then asked to elaborate on comments he made the other week in which he teased a “bigger enemy to fight” in the followup “Justice League”:
“Well, you have Doomsday, right? He doesn’t just crawl out of the ground. He has his own mythology, right? So that has to be explored.”
