You we're born in the wrong time frame. Citizen Kane was and in legacy is a great movie in many ways, but to today's audience it's just some old movie.
It's akin to growing up with a PS2 and wondering why everyone gives DOOM so much credit, its graphics are shit, the music is bland and its not scary in the least, but when it came out it was groundbreaking, scary and controversially gory.
This is a good example, but I would compare it more to Star Wars. Many of the kids growing up now think it's boring, especially compared to the prequels (Isn't Jar-Jar awesome?), but they don't understand how life-changing Star Wars was before the overuse of special effects (*cough* green screen *cough*). (Sorry, btw, your example was great. I just felt compelled to compare it to a movie.)
OT: One of CK's best points is its use of dramatic irony, which is really accentuated by the cinematography. It's not overdone, either. We know what's going to happen, but he doesn't, so as we identify with this character, we're also watching his downfall. He is a tragic character, in the most traditional sense.
Orson Welles also portrays the irony quite clearly with his cinematography, also. Using techniques that are now trope, but were then unheard of, he allows us the privilege of knowing things that the characters don't, seeing things that they miss. He uses the "unmotivated close-up" to great success, allowing our minds to make connections. While some of the things may seem boring, were you ever taken out of the world he created? Personally, I thought he did a wonderful job convincing the audience that these were real people, with real ambitions, real flaws, real emotions, and real connections.
But that's the key, isn't it. Personally. It's an opinion. Maybe a commonly held one, but an opinion nonetheless. You've heard my reasons for liking it.
