I never liked Citizen Kane that much. Direction, cinematography, camera angles were inovative for that time and I can understand why it's important from historical perspective. But the story leaves me cold. On the other hand, 12 Angry Men or Casablanca are masterpieces in my eyes.
That's the other thing to keep in mind, seeing things in perspective for the time; these movies were literally groundbreaking, like Wizard of Oz' transition to color film (compare with e.g. Avatar which popularised 3D film), Jurassic Park's use of CGI blended with models and live actors, the unfortunately one-off Who Framed Roger Rabbit, Toy Story's full CGI film that revolutionised animated filmmaking (arguably for the worst since it eventually came at the cost of "traditional" western cartoons).
It feels like it's getting harder to do something new.
