meh, not a huge deal... so a movie is being made and people will protest saying it's against good tase and news agencys will talk about it for half an hour then it'll die down.
so what? Sure 911 sucks, people died and I'm sorry for the loss of american, canadian and other passangers lives. But it's over, it happened, it's done and it's over, it's been over for 5 years and we're still here and we're still alive.
get a ticket, buy some popcorn and enjoy a movie, WWII movies are a dime a dozen and they are based on a real war, LOTS of people died in them too, but meh. I most likey won't waste my money on this movie, I'll just wait until my brother can get it as a free rental and pick it up then, who knows, you might learn more about it then you knew.
