It's the nature of big budget film making these days. Studios are not willing to throw millions of dollars at projects that aren't going to see them a sizable return. So when someone brings them a reimagining of a movie that brought in huge profits, or a script involving a big nostalgia property, they get dollar signs in their eyes. Even if the movies are not well received (see the Transformers franchise), they are still going to make money on the opening weekends for people going to see if it lives up to what they remember. Sometimes it works well, see Mad Max Fury Road. Sometimes it's a terrible and should never have been made. See Battleship.
Studios are only going to make what earns them money or acclaim. That means remakes and imaginings... 'fanfiction'. Adaptions of popular book or television properties. And vehicle movies for popular stars. Plus more 'artistic' films around Oscar season. Any other projects have to squeeze in. Usually either supported by someone who has a lot of clout in the industry, or funded by smaller studios more willing to take risks.
In some ways it makes me glad I didn't follow through with my dream of getting into the special effects industry, so I didn't have to deal with the politicking involved. Mostly though it was the huge amounts of time on location, and the on/off nature of the work. I need more stability in my life than what working in a special effects studio could offer.
