"Ember Days" on Tubi - I don't recommend this movie, at all, unless you want an education on a particular subset of film makers, or are considering doing independent film yourself. Some independent film makers are of the opinion that they can do it all, not because they are trying to save money, but rather because they honestly think that anyone else would screw up 'their vision.' Writer, director, producer, star... Think of movies like "The Spirit" but with Frank Miller being even more full of himself, with zero self awareness. Take a look at the movie's IMDB page and you'll understand what I mean. I say this, despite a good friend having been in this... thing. The people I know, who make successful independent films, know that they need to get out of the way and let skilled professionals fill roles like director, screen writer, etc., and hire them.
As a counter-example on film making, it's excellent.
