A very large portion of well funded, early stage startups that crash and burn in LA are typically because media people have a hard time conceptualizing lean startup, and rapid iteration etc. Over the years I've accepted it's not so much hubris as it is entertainment is just a different industry with a different way of doing business and people who found success in entertainment think that method they achieved translates to tech startups, when it unfortunately doesn't.
In Hollywood you put all this time and money into one big event like a film, or an album or a pilot and people scoop it up due to marketing. They consume it, then they are done. If they like it they ask for more. So if you have the money you spend all of the money at once to make the best thing possible, put as much marketing and PR against it as possible and people will consume it anyway. Usually you make some of your money back. If consumers ask for more, that's a bonus. Then you go out and raise more for the sequel or the next album or whatever.
Of course tech is different - you can't put all that money into the first iteration and expect it to pay off. You need to stretch it out over many experiments and control burn over years. It's just a totally different financial model and business plan. There are so so many Quibis out there that never got past private alpha / beta. The execs spend YEARS crafting that perfect alpha, open it up privately to friends and family, it flops and then they throw in the towel just like that. I've seen it more times than I can count now
