Not a thinking persons SciFi.
At least one poorly constructed sequence.
Cinematography and acting was all pretty good, maybe very good.
Writing, editing, maybe even directing, not really very good.
As a fan of SciFi movies and TV (haven't really read much), as well as Science and philosophy, there were a great many missed opportunities here. Sadly. However Amy Adams was very good and Jeremy Renee was perhaps only somewhat behind her.
I suspect that everyone else probably showed up on time, hit their marks and knew their words.
She unraveled the mystery of her own memory through deciphering language. There was no concept of tense, and the idea of including the future at one point was somewhat fresh for me.
