Although I would never bother to sue over it, I assume this is the new normal. Does anyone remember the movie "9"? The trailer had puppets fighting robots to the tune of "Welcome Home" by Coheed and Cambria. It looked awesome.
That was perhaps the most disappointed in a movie I ever was. Not only were there very few of the fight scenes that weren't in the trailer, but the song never played during the movie. Just the credits. What's the point?
