Re: The least disliked episode of DS9 - Season Four
Starship Down - the others are much better. Out of the various plots, only the one with Quark and James Cromwell was interesting.
Return to Grace
The Visitor wins it. I love Return to Grace, but frankly the Visitor is quite possibly the most emotionally moving episode of all Trek. The love of a son for his father.
