This has got to be one of the strangest story arcs done on DS9, that's saying something.
It's not that it wasn't entertaining on some level (18-year old Molly is really hot and way, way too well-groomed). I just have no idea how you arrive at this sort of plot. Plus, what the hell is a functioning time portal doing in a Bajoran meadow... and why doesn't the federation take more interest in this obviously advanced technology ? And what is this never-before-mentioned super race from ancient Bajor ? Also, the ending was a total cop-out. It should have ended way more harshly.
