I just recently saw the film, Across The Universe
], and I really enjoyed it. The movie didn't have a great story or anything, but this film isn't about the story, or the actors - or even the music. It is all about the images, the art direction, the photography, the lighting, and the sets. It is was you would call a "visually rich" film.
The story is punctuated by several different Beatles tunes, each acting more or less as and individual vignette or microcosm that in many cases does not adhere to a general theme. This gives the film kind of a choppy uneven quality, but I think that this factor made the film more interesting. Several of these vignettes are quite striking and surrealistic, most notably "Happiness Is a Warm Gun"
and "Strawberry Fields Forever".
It has always been my opinion that an image can express an emotion far better than many pages of dialogue, and communicate with the audience on a much deeper level than in film, bad images will quickly kill a good story, but good images will elevate even a bad story to new heights that the author hadn't conveyed with the written word.
Imagine if Star Wars had been produced with the same level of visual as the original Battlestar Galactica, I doubt that people would be talking about what a wonderful story it was, despite the cheesiness of the art direction. If the film Alien had been produced with the same level of art direction as It Conquered the World, it would have been just another cheesy science fiction movie.
That said, even though images in film may convey more than dialogue, or in some cases more than the story itself - the script is still the most integral part of any film. But sometimes I can enjoy watching a film just for the pretty pictures.
