This is really a list of historical ground breaking movies.
Citizen Kane hasn't held up as well as film buffs like to think.
Vertigo is a good but not particularly memorable thriller. Psycho is way more important.
The Wizard of Oz, like Citizen Kane really only stands out in context of its time.
Casablanca and Lawrence of Arabia are truly great movies even today. I'm not sure anyone has ever really recreated Cassablanca's magic.
