definitely no need for the 'ignore list'
unfortunately there are rules that govern 2 dimensional composition and design that unless you have been through some sort of specific schooling or have an thirst for such knowledge, most overlook. from the colour wheel down through such banal ideas like Gestalt, the core logic exists and through that logic, an individual can certainly designate a photograph as either 'good' or 'bad'. there are few, if any, great photographers (past or present) that ignore this core language.
at some point the idea that 'art' is entirely subjective falls short. primarily this happens due to an ignorance of these theories and their historical development.
