The Shape of Water is an artistic period film that aims to redefine what's socially acceptable, with great acting and even a dash of sci-fi. (I'm a Michael Shannon fan from his Boardwalk Empire days. Richard Jenkins and Sally Hawkins do a fine job as well.)
Authors spend months, sometimes years, compiling their words, in an effort to create something they can share with pride. So as I'm sure you can imagine, the decisions that go into that thick piece of paper that surrounds it all are neither quicker, nor easier.
I saw a tweet earlier today about Judge Dredd, and it reminded me of a lot of great sci fi that I've seen that hasn't been a Disney property or epic blockbuster. Ex Machina is a great example of a recent film that falls into this category.
