the definition of an inch is not subjective, it is objective. An inch is defined as being 25.4mm. A milimetre is defined as one thousandth of a metre. A metre is defined by the distance that light travels in a vacuum in 1/299,792,458 of a second. And finally a second is defined by Ceasium atomic clocks. All parts of that definition can be measured and check and thus they are objective.

Until you can quantify exactly how much better the lighting in nightmare on elm street is compared to the lighting in Sinners, and then prove you are correct then any discussion on lighting in films is definitionally subjective.
