In a conversation with a producer and a screenwriter after my first film consulting contract, I quickly learned how much more attractive realistic scripts can be to potential directors. The fact that the film industry is actively embracing subject matter experts not only for establishing overarching themes and very central elements to plots but also to accurately represent even the most minor details is a fascinating turn in the last twenty years of filmmaking.
Minor details in the case of this film might be things like deciphering written sentence structure and realistically assembling new sentences. Minor details in the case of e.g. the matrix might be the use of SSHNuke. It's just nice to see.

As for Arrival, it was easily one of my favorites this year, if not one of my personal favorite film of the last five. You should see it it you haven't. It's easily one of the most emotionally complex films we've had in quite a while.
