I liked how the Dixon Hill short opening tied in with the main mystery plot. This is a well structured and paced episode that is just missing a few pieces to become a classic episode. This episode suffers from diminishing returns on re-watch. I would need a time machine to go back to the 1990's to give you my opinion of this episode knowing nothing going in --- that might not be fair but it is the truth that previous knowledge does effect my enjoyment of this episode. I can and do enjoy mystery episode even if I know the solution going in but typically there are other elements that have me hooked to accompany the mystery elements. Well, it is Sci Fi --- and it's nice to get sci-fi elements from time to time in a show with a sci fi underpinning.
