Boomers yelling at AI generated cloud. I personally don't mind it, being an intro only. It doesn't look bad, it looks fitting. Could a human artist do a better job? Maybe. But I feel like this was an art driven decision being an AI tool used to create the intro. So a human artist is the wrong "tool" for this job, based on the vision and idea to use AI.
Me, the consumer, don't care much how it was created. I judge the final product only. However, I am not a fan and not an artist, so my view is not more or less important. But it feels to me like this is getting a bit too much hate. Maybe the AI tool was used as an additional marketing gag, so people talk, report and watch the movie.
