Re: I thought Arrival was decent.
>yes, all that was evident in the movie. Still comes of as "bam, time travel, done"
Most time travel movies have the plot: "Find or invent time machine. Travel in time. Mess with something. Discover bad unintended consequences. Try to fix it. Fix it. The End.*" Arrival was not like that.
*Of course we get themes and variations, where multiple time loops get invoked, or the bad stuff can't be undone. Perhaps the best of these is Primer.
