Description :
More purely science fiction than the sci-fi/horror hybrid as seen in first season (no more "scary monster of the week" recurring motif), the 17 episodes in this second and final season featured more action as well, including two classic episodes written by Harlan Ellison. Guest stars include a pre-Star Trek William Shatner and a pre-Batman Adam West.
