It's lousy. Slow-moving and formulaic. At the Wall Street Journal's private Core Club screening earlier this week, not everyone lasted the two hours. One slugged it: "like a made-for-TV job." It hops back and forth from a scene of cops buried under rubble to a scene of families awaiting word, to a scene of computer-created devastation, to a scene of reaction shots. Back and forth. Back and forth.
It is way too soon for a movie about what happened at the WTC. Oliver obviously wanted to be the first to attach his name to an infamous day in American History. NYC didn't allow him to have access to any shots below Canal (WTC was waaay below Canal.) The commission made sure it was as hard as possible for Oliver to shoot this movie, and it shows on film.
The movie sucks. Don't waste your time.
