The word is ********.
One of the many cut or unfinished scenes was after Sandman gets hit by the missle and collapses, his dying daughter shows up(another cut scene reveals that no matter how much money he steals and gets to the doctors, his daughter is dead regardless) and hugs him and convinces him not to fight anymore. Which is why he just stops fighting after his giant avatar gets destroyed and isn't seen until after the rest of the battle is finished.
This movie- and the ending especially- get a lot of crap, and while I'm a big fan of the movie I agree with the ending having tons of problems. Not that your or anyone cares, but in my ideal world the film would have ended with Gwen in the car, Harry deciding to show up on his own without Bill Paxton's dad OR Mary Jane explaining things to him and asking him to help, Venom biting Sandman and Sandman dying, then Topher getting locked away for future stories. But hey, I'm just no one on the internets, and they get paid big money to make movies, so maybe I'm wrong.
