spoilers ahead I felt like the character conflict arcs were contrived and ultimately the idea of learning a language makes you a pre-cog fell flat for me. In science fiction, the big idea goes 'woo!' or the characters go 'woo!' but in the case of Arrival, nothing really went 'woo!'
But maybe I'm wrong - what was I missing about Arrival?
In Arrival, the 'woo' is basically in the last few minutes of the movie, when it's revealed that the mission only lasted moments but the audio recorder captured hours. If you blinked, you missed it.
For me, personally, Arrival ranked up there with Interstellar.
I'm of the opinion that you have to give older movies (pre-2000's) some latitude. Writing, continuity, and character development all evolved substantially after Arrival came out.
I think you might be talking about Contact, not Arrival? Contact was the one where there was a mission through a wormhole machine at the end that had a discrepancy in how long it lasted based on how much static the audio recorder collected. Arrival was the one with the linguist trying to figure out how the language of the visiting aliens worked.
You're absolutely right. Got my one-word-scifi-movies mixed up. Thanks for the correction. I went ahead and deleted my comment. Apologies for the confusion.
