Yeah the Godfather is an absolute masterpiece of a movie, with every component being perfectly, or near perfectly, excecuted. I can’t comment on Mozart as I haven’t yet seen it but is on my list to do so now. However for me the Godfather doesn’t hold the top spot. In my opinion top spot goes to 2001: A space odyysey. I think it’s kubrick’s best work. The cinematography, the score, the editing, the themes it disccusses and the quality of how it does so is so utterly beyond any other film for me. There are many other greats I love; almost any other Kubrick, any of Quentin’s, and the classics by Billy Wilder and Hitchcock to name a few directors that put out fantastic work. however for me it’s 2001 a space odyssey that wins it.
