Personally, I care little for influence. I understand the position and I say this with ALOT of classically important films, books, and music nearby including CK, but personally I feel personal aesthetic value is the only value. Now, I think it's undeniable Orson Welles was a great director, but ultimately anything he did would have happened with or without him eventually...someone would have thought to do a ceiling shot sooner or later. Moreover I think most any director (or any other artist for that matter) would prefer that you enjoy their creation than think it important.
