It's not an especially rational piece of work as such, although it has its moments, but it is one of the more detailed examinations of heroic responsibility and the associated cultural expectations in fiction (if you can get past the sometimes shaky translation). Your mileage might vary, but I see echoes of it whenever Eliezer writes about saving the world.

It has some elements that stand out in terms of rationalist virtue, and many others which don't.

I found it to be very much a mixed bag, but the things it did well, I thought it did exceptionally well.

It's not so much rationalist as... Eliezer-ish. See my review in the media thread: http://lesswrong.com/lw/i8c/august_2013_media_thread/9ilm
