Lets clear a few things up.
Object A: Its not called "September 11: The Movie", its called "World Trade Center"
Object B: The point of the story is NOT to explain what happened on 9/11, its the story of a trapped dude, 2 more specifically.
Object C: It wasnt meant to show the devastation, the planes crashing, the building falling, ect.
Object D: Sure there are better 9/11 films on the internet, but this isnt a 9/11 film. Its a story about a guy and his homie trapped under a lot of shit.
Object E: Its a survival story, at best.
