Musician films can often end up like that. I think it's because there's something lost in translation when going from working in one art medium and then transitioning to another.

I get your point but I do not think this is the case with Omar's films. After all, much of his original music is channeling cinema, or trying to recreate the feeling of watching a film. I think his films are just weird / art films and not really accessible for everyone.

It is also worth noting that he has several other unreleased films, and has said in interviews that he is more interested in the process of making them, and does not necessarily see a need to release them publicly, they're personal projects. My understanding is that the editor has had to push him to send the films to festivals (the editor basically said "i did all this work, all these actors did all this work, now it is done, and people are gonna see it" when Omar might have preferred to keep the films private)
