I wrote indepth reviews of the four sections of NXE over a period of several months after reading Apotheosis Now, and posted them on the review page of my website: http://www.freewebs.com/celestialwombat/reviews.htm
Apart from some problems at the beginning, I loved NXE - it's one of the best works of fanfiction I've read. Being a) a hopeless romantic and b) a Rei fan, I particularly liked the Jon/Rei relationship.
