There is an extensive and detailed support of the NWT by A. Byatt and Hal Flemings: Your Word is Truth: Essays in Celebration of the 50th Anniversary of the New World Translation. It is worth a read. My mom detested Byatt, seeing him as a self-important man. Flemings is a professor at UC Santa Barbara who teaches ancient languages, and is someone Uncle B knows.
I know nothing of Greek or Hebrew. So I do not know if any of the arguments are good. Mom, who had two years of Biblical Greek, saw it as a mixture of amateurish and really good essays.
