Lost Elements from TOS.How much changes in the Star Trek universe in 100 years? When The Next Generation first aired in 1987, viewers discovered a new Enterprise, a new crew, as well as writers and producers who wanted to "update" several aspects of The Original Series. In this episode of Earl Grey, Daniel Proulx, Darren Moser, and Phillip Gilfus discuss which elements from TOS were purposefully avoided, and whether it was a mistake to "reinvent" Star Trek too much or if it helped TNG create its own unique identity as the newest Star Trek television series.
