I wasn't a big fan of the animated series - I wanted more "real" ST eppies! It did have its moments, tho.
As
I mentioned previously, one eppie really intrigued me: "The Slaver Weapon". Then, as a young adult I read a Larry Niven short story collection that included "The Soft Weapon", and recognized the basic plot, premise, and also antagonists (Kzinti) not found in the
Star Trek universe, but imported from Known Space!
