8. Doomsday - Batman V Superman: Dawn Of Justice (Trailer 2)
It's kind of difficult to pick just one spoilerific moment from the Batman V Superman trailers, given that - together - they appear to spell out every single beat of the movie (sigh). Still, the most annoying and ill-judged inclusion in the collective trailers to date is that of Doomsday, who could have remained a neat little secret (aside from all the speculation that has surrounded the chance of him turning up) until the film shipped into theatres. Instead, he's already been revealed as a further villain in an already packed-out picture.Not only does Doomsday's appearance in the trailer tell audiences that Batman and Superman will eventually put aside their differences to face a common threat (it was obvious that they would, but c'mon - not as obvious as it is now), but it ruins would could have been an interesting and unexpected third act twist. The film already had Batman fighting Superman, Warner Bros. - Doomsday wasn't necessary to sell the movie to us! Our money has been in your pocket for months!
