They say 9/11 movies have not done well. Maybe people don't want to re-live the horror. However, while this revolves around that day, it has more to do with a small boy's adventures and with him coming to grips with his love of both his father and his mother.
A little slow in the beginning, the movie picks up a lot when "the renter" enters the film and just gets better and better. Fabulous acting and very enjoyable, it leaves you thinking a lot about how that day affected a lot of people.
