http://www.rottentomatoes.com/m/united_93/It will be interesting to see how this plays out politically. From the Village Voice review (warning, there are SPOILERS):
Paul Greengrass's approximately real-time dramatization of what took place aboard Flight 93—which left Newark for San Francisco the morning of September 11, 2001, and crashed in western Pennsylvania 81 minutes after takeoff—is best understood as a memorial. (It was famously made with the support of the passengers' families, the press kit includes bios not of the actors but of the people they portray, and Universal is donating 10 percent of the first weekend gross to the Flight 93 memorial fund.) Like most memorials, it is respectful, premised on competing obligations to the dead and the living, and eager to stress that the deaths were not in vain. It not only tells us we should never forget but also illustrates how we should remember....snip...
United 93, in providing a coherent and vividly edited macro timeline of the day's hijackings and crashes, is a uniquely damning description of the chain-of-command failures and communication breakdowns that characterized the official response to the terrorist attacks. The film suggests that if the FAA, the military, and the airlines had been talking to each other that morning, Flight 93 need never have left the Newark tarmac. When it took off at 8:42, at least one hijacking was already well under way (American Flight 11 hit the north tower at 8:46). Twenty minutes earlier, the Boston control center had received the first suspicious transmission from the first hijacked aircraft: "We have some planes." (United 93 dispels the most popular conspiracy theory by pointing to incompetence—the plane wasn't shot down because the government was too stunned and unprepared to have done any such thing.)...snip...
Perhaps mindful of his target audience, Greengrass makes sure to dangle some red-state red meat. In the blurry rebellion that is United 93's raison d'être—a spoiler follows—the passengers appear to kill two of the terrorists. It's the most problematic of the movie's unverifiable events, and one might say its biggest concession to popular taste. In dramatic terms, it's the only instant of catharsis. This act of self-defense may have happened, and the filmmakers are entitled to wish it did. But United 93 slips into propaganda with a concluding title card that declares, "America's war on terror had begun." Whatever Greengrass's intentions, his film's closing moments essentially memorialize 9-11 Bush style, as an occasion for revenge. Painful as this movie is, it's even more excruciating to imagine how it might play in some of the country's multiplexes.http://www.villagevoice.com/film/0616,lim,72901,20.html
