The Spider-Man reveal,
and the Doomsday reveal.
Yesterday I argued they were one and the same.
But many of you offered a compelling counter argument
saying that while the two reveals are indeed similar
and perhaps both a mistake
there's a crucial difference!
And that's that Doomsday was merely a rumor
for Batman v Superman Dawn of Justice
that had not been confirmed until he appeared in that trailer.
Whereas Spider-Man was already confirmed
to appear in Captain America Civil War
so it wasn't quite as spoiler-y.
