Interesting. The film isn't as insightful as I thought it would be, Amy Adams' performance was much overhyped, and no, the soundtrack didn't deserve an Oscar nom so stop saying that it did. For once the Academy was right.
The film's timeline is interesting, and used in a neat little mystery, ticking-time-bomb scenario. All things we've seen. The first-contact premise has literally been 50% of Steven Spielberg's filmography, which is huge, so that genre is already a little over-spread. I guess Dennis was just practicing for "Blade Runner: 2049", which I hope to God is better than this.
