Back in 1995, the studio Gainax, under the leadership of Hideaki Anno, made Evangelion. This was widely agreed to be an epochal thing, and Gainax was hailed as a great studio. They followed up with a series of other critically succesful works - FLCL in 2000, Diebuster in 2004, and Gurren Lagann in 2007. (Which is not to say that all of their works were great - but some of them certainly were.)
Today, it is often said that Gainax has fallen from grace. Their recent works are... somewhat less epochal - Houkago no Pleiades in 2011; Medaka Box in 2011 with a sequel in 2012; C3-bu in 2013; and (currently airing) Magica Wars in 2014.
This motivates the following question: is there anybody left at Gainax who worked on Evangelion back in 1995? It's often claimed that a large part of Gainax (including Anno) left to form Studio Khara (for Rebuild), and that the rest of the good people (including e.g. Imaishi Hiroyuki, i.e. the Gurren Lagann people) left to form Studio Trigger. If it is, in fact, the case that there's basically nothing connecting 1995 Gainax to 2014 Gainax besides the institutional name, that would do much to explain Gainax's "fall".
