Yeah, the "save one" dialogue from Batman to Flash. There's no way he just pulled that out of thin air.
I remember reading what he wrote, and some of it sounded good in theory, even the opening scene with Superman and the homemade video (though he did say Cavill had the 'stache during that scene when he screened it), but then he gave away certain lines that made me think, "Okay, you had people going, but there's no way 'THIS' line is in the movie," stuff like that, that made me wonder why he went from trying to trick people to then flat out trolling people.
Only 'THOSE' lines WERE in the movie and he WASN'T trolling people. Sigh.
