For example, why did Reed have to say, "Oh, Galactus wants the baby," to the press? Would Reed, the smartest man on Earth, really say that? Fuck no, it's to create conflict, of course, and all it does is to have Sue have her "moment" with the protestors.
I was almost invested at the ending when Johnny was about to sacrifice himself. But of course, they pussied out and had the Silver Surfer sacrifice herself instead because we just have to have a happy ending. If they had any balls they would've had the Silver Surfer ready to sacrifice herself, but Johnny says what he says, and pushes her out of the way and delivers the blow to Galactus.
Have Sue come back to know that Johnny is gone, and have her lash out at the Silver Surfer, who doesn't know what to say, and runs off. Everything has to be a goddamn happy ending these days (yes, Viktor comes and steals the baby in the post-credits, but I don't count that). Have Johnny come back in the Avengers, or something, but man, the ending sucked.
