There’s no way in hell that she would’ve learned that amount of the aliens’ language in such a short time frame. But that is a minor quibble. And ironic, in a movie about time travel. Or is it simply seeing the future?
Amazingly gripping, when so little really happens. But maybe that’s just the former language teacher in me speaking. What’s really different about this, in terms of a modern science fiction film – or really just about any genre these days – is that it’s more interested in the underlying ideas and philosophical questions that arise when we make contact with aliens – or they with us – than in intergalactic warfare or conflict in general. The only ones fighting here are the humans.
