this documentary be interesting and but it be also long ( so long it last a total of 225 minute ) and like ben hur long . but if your into that and this be for you . but only if you have a passion for movie and like i do . be that martin scorsese be my favorite director ( live and maybe even ever ) and this be quite fascinating and especially if you know the style of scorsese work . because then you can understand where he get his inspiration for many of his film . not the best documentary film ever make and but it be a leap for scorsese and which be always good to watch . a .
