alt Hacker Newsblair witch project looked like shit, 'the cinematography doesn't approach a true director of photography', the actors were shit... etc. Given the right script and concept it can be amazing and the imperfection of AI can become part of the aesthetic.
It was still a creative stroke of genius. The shit acting along with the shit cinemotography was preceded by a brilliant marketing campaign where you expected this lack of skill by the film makers.
In music you also have plenty of artists that have no clue how to play their instruments, or progress their songs, but the music is nonetheless amazing.
Skill is not the only quality of art. A brilliant artist works with their limitation to produce work which is better than the sum of its part. It will take AI the luck of ten billion universes before it produces anything like that.
