Citizen Kane is arguably one of the greatest films ever made for many reasons. It was one of the most controversial films of its time, but the controversy is not what made it great to me. I think that the many tactics in film that Wells used and are now incorporated in virtually every film are what make this film truly one of the greats. From the crane shot of the bar where Susan Alexander works to the intense contrasts in lighting in Xanadu scenes to the overdubbing of sound in many scenes are what make this film not only great, but ground breaking.
