I hate to admit it, but I don't think that Second Sight is all that bad, though it's not a four or five star episode by any stretch of the imagination. It probably could have been improved by giving Seyetik more complexity and humanity rather than simply portraying him as a pompous overbearing jerk who laughed way too hard at his own jokes. Sisko's instant infatuation with Fenna I can accept. You just have to keep in mind that the poor guy likely hadn't been laid in four years and that Fenna was smoking hot.
The view of the station from the upper docking pylon was a nice touch.
