Needs better editing
This could have been a very good short film, as there are several scenes that I think were successful in showing who Crane was, what he wanted to do as an artist, and the struggles he faced.
The problem is that there wasn't enough of that material to fill out the full hour-and-a-half running time. So there are long sequences of nothing particularly interesting happening, which hurts the pacing and makes parts of the film seem unfocused and a bit boring.
One example was the shots of him at the beginning of the film showing his head from front, rear, and sides (I assume this was done to indicate that James was playing an older version of the same character as Dave had played in an earlier scene, which had similarly shown the character from front, rear, and sides). This scene just seemed unduly long. Another example was the scene in which he appears to be writing a poem and is meditating on a word (sounded like naugahyde, but I don't remember exactly what the specific word was). This scene just seemed to go on endlessly and pointlessly.
I can see why many viewers haven't liked the film, and I wonder why Franco made the editing choices he did. I think if it were re-edited, it could be improved quite a bit.
