This fanfic has horrible grammar, several characters are very different from their canon counterparts (ranging from Alternative Character Interpretation to... well, this fic's Gendo), a few characters receive a rather thorough bashing (Gendo is portrayed so badly and goes through so much abuse that this probably counts as a Revenge Fic), and the relationship between Lee and Rei seems somewhat rushed (especially early on). That said, the characters are mostly internally consistent, the story draws very heavily on the Rule Of Cool (and manages to pull it off), the fic has actually been completed with a proper ending, and the fic's premise is so awesome that it makes it easy to look past all that other stuff. Once you've read a few chapters, the fic becomes very difficult to put down until you've finished it.
FanficRecs Pretty damn good, all things considered
