I read several years ago that 'Hollywood' (I think in this case large movie studio executives) had spent millions researching what kind of movies were most likely to earn positive return. The ultimate answer - other than creative fair that audiences love (which they were already pretty terrible at predicting ahead of time) was 'sequels.'
I was listening to a James Cameron interview where he said much the same thing. That Hollywood executives are dominated by the risks of big budget films and make movies largely out of the fear of missing out - that another studio will have a blockbuster while they have a dud - rather than motivated by belief in a creative product and it's quality. The result is that original, story-driven fair is almost impossible to make (in Cameron's opinion), while executives constantly look for projects drawing on existing intellectual property that provides supposed built-in audience, buzz, and fan base.
Cameron said the silver lining was the emergence of phenomenal television. Non-network television has proven the model for creative, original, high-production value programing with Breaking Bad, Game of Thrones, etc. He said if he were starting out today he'd work in TV not movies. Accordingly he said TV like that is generating top writing, directing, producing, and acting talent for the shorter-series (8-12 episode) projects. He said on TV executives will give producers/show-runners (who are more analogous to directors in movies) much more leeway and time to develop characters, story, and plot than a movie studio would ever give.
Don't get me wrong, there's still a lot of shitty stuff and unoriginal 'revamps' on TV - but I think with the success of great TV the last few years and the push into original content by streaming services and pay-channels the TV quality is only going to get better and better. I think Steven Spielberg wrote a few years ago - and Steven Soderberg has said much the same thing - that the Hollywood big studio economic model is one bad summer of blockbusters from going broke. Maybe the international market changes that calculus but I'm not sure.
