Update 03.04.2017 - I really need to start taking some time to absorb before I write these things, because my original thoughts don't do this any justice. As much as I enjoy short story collections, I hate reviewing them, because there's just too much. 
 I've bumped this between 4* and 5* so many times because I'm not sure how I feel about it in the end. Ken Liu is an extremely proficient and versatile author, and he has a lot to say. From privacy concerns in "The Perfect Match," to the technological rift between a father and his daughter in "Simulacra," to the poignant insights into history offered by "The Literomancer," "All the Flavors," and "The Man Who Ended History." In particular, I loved "The Waves." It gave me chills, to look at this ark of humans who, at the end, aren't necessarily what we recognize as human at all (or are they?). 
 But, (and there always seems to be a but), there are times when he doesn't quite meet the mark he's set for himself. Times when the characters or the execution fall just slightly flat, and it's enough to prevent me from calling this collection "amazing." 
 Final rating, 4/5.

 (Original Review) 
 Short story collections have grown on me over the last couple years. They're filled with perfect, bite-sized chunks of literature, and they offer a good overview of an author's writing style and interests. 
 This collection is lovely, crossing genres easily to showcase Ken Liu's skill with words. Of those stories that I had trouble *enjoying* ("The Regular" and "The Man Who Ended History" come to mind), I still appreciated their underlying message. 
 Excellent showcase. May expand on this later.
