People often throw around the title of "Greatest Film of All Time," but to the untrained eye the film itself seems unremarkable in that capacity. What's so great about Kane is the subtleties and nuances that make it what it is today. In addition to its many innovations, it marked an important time in cinema: a culmination of the achievements of the films that came before it and the future for the Hollywood industry for years to come. Only with time and distance did Citizen Kane really get the credit it deserved. The film failed to make its money back at the box office initially and took several years to gain the critical acclaim it carries today. It didn't even win the Oscar for Best Picture that year (although to be honest, many films have had this happen to them--more here and here).
