The problem here, is the studios, who keep messing the original ideas of the screenwriters and the directors. It's like Sony didn't learn after Spiderman 3. The article mntions Harry Potter, but Warner never cared for the franchise, and cut lots of scenes from the books, scenes that were going to be filmed, and some that were filmed but wanted them to cut because they were too gritty.

The studios doesn't want to take risks and wants to be in charge of every project, controlling the filmmakers, to make sure that the films can be profitable, instead of letting them to be as the directors wanted to be in first place. How many book and animated franchises FOX has botched because they wanted to make money? Most of filmmakers on these days are turning into hired guns, people who can't make their vision of a story coming true because otherwise, they're bashed (Like Shyamalan, who went from doing personal films, to products like Airbender and After Earth because of the people bashing his risky -but original- ideas).

And notice how some of the recent franchise reboots of the past 5 years have crashed because of messed up sequels (ASM 2, The Muppets 2, Star Trek Into Darkness, The Dark Knight Returns), ruining a new take of a old story because of fanservice or interference from the studios.

And by the way, for the bit of the article mentioning about Hunger Games, read Mockingjay.
