Obviously any list like this is going to be very subjective and this one touched off a fiery debate around our office.  We (almost) all agreed that (almost) all of the films on this list (it's actually a pretty cool info-graphic) deserve a top ten ranking especially if you re-named it, "The Ten Best Old Or Really Old Private Detective Feature Films".  Our crew believes that at least two, other, more current films also have to be included:  "8 mm" and "Gone Baby Gone".
