i rent this for my son who be recently find interest in 9/11 . he be a kindergartener at the time and have no idea what be unfold . i like the way it be tell a a documentary . if there be one movie that i would recommend to see concern 9/11 and this would be the one . normally you see a movie it have actor that be well know . this movie have nobody know . also and you see a movie concern 9/11 and you hear about a fire fighter or two lose their life save people . i do not feel this have any of that . i only rent this movie and would definitely consider add it to my collection . very well do indeed . my heart go out to the survivor and family of victim of 9/11 .
