Has anyone seen "Jurassic World"?

[Pyrrho]

Oh well now I've seen it, too!
...  Ordinarily one would think that with a 150 million budget, there should be some money in it for making a good film, but apparently that's just not the objective any more. Jesus, does sensible dialogue cost a million dollars per word or why is it so hard to come by. Some things though are so incoherent that one wonders whether the put the movie together in a different order as originally intended. Weird!

Good stories have always been problematic for Hollywood.  Good writers are not as common as one might want, and those making films typically cannot recognize good writing if they trip over a well-written book.

In some cases, good films have been made by taking a story from a good writer of long ago and making a movie of it without changing it too much.  But idiot filmmakers like putting their stamp on their films, and so they like to fuck up the writing even if they managed to stumble onto a decent story which they have adapted to film.

Or to more directly answer your question, good writing requires some intelligence, and that is something that humanity does not have in abundance.

If you want proof that most filmmakers are morons, buy some DVDs or BDs of films with director commentaries, and watch them that way.  With very few exceptions, one finds that filmmakers are idiots who would have made something even worse if they had not had help from others who were not completely incompetent at their tasks.

I can think of one director whose commentaries do not give that impression, and that is Werner Herzog.  Ironically, you are not very familiar with your [former] countryman [he now lives in the U.S., or did the last time I checked].  His films do not have the biggest budgets, and that affects the final product, but he is always interesting, at least in the films of his that I have seen.  In the case of Herzog, his films are interesting with his commentaries.  With most directors, I turn off the commentary within 15 minutes, as I cannot stand their moronic comments and their incredible stupidity.  But, viewing films this way does explain why so many films are so very lacking in so many ways.
