Books, on the other hand, sometimes are subject to criticism. Criticism explores, interprets, and analyzes. It asks "why" and "how" questions. The best criticism expands and changes its subject. Literature as a culture has its roots in both original work and criticism. Almost as soon as there were works to read, there was literary criticism. (The Talmud springs to mind as an early example.) Certainly, most readers and many critics are more interested in reviews than criticism, but the feedback from criticism has been fundamental to the development of literature.
This balance makes literary culture much different from gamer culture. Even with games aspire to be art, the reviews go like this:
The game explores themes of identity and abandonment. Who are we and how are we separate from each other? It might be art. The controls are a bit laggy and the game is only two hours long, which isn't great value for $10. I give it an 8 out of 10.
I've read a few game reviews that go farther but these are few and far between. Maybe the recent controversies will start us down a new path.
EDIT: I wish HN had a preview button.
