fired for real. The 3-4 biggest points in the film were ruined by the trailer.

First the fact that the trailer SHOWED Batman and Superman teaming up took all the tension out of both the buildup to them fighting and the actual fight itself. We KNEW it was gonna be all good by the end, which is bad since the name of the film is Batman V Superman.

Second it showed us Wonderwoman, which ruined her reveal coming to save them. The whole movie when she was investigating as Diana we already knew who she was so the reveal fell flat.

Third, the trailer spoiled Doomsday. Honestly the film itself just wasted Doomsday by having him tagged on the end and killed when it should have been BVS, but the fact that he was in the trailer made it worse.
