I've rewatched it several times ... it's supposed to explain that Sisko's part Prophet, that he was created in a mix between god and human (like one of the Greek myths, I guess). Didn't care for Ezri much though.
I was able to appreciate the two light-hearted eps -- Take Me Out to the Holosuite (Odo's great as an umpire ... just watch his reaction when somebody hurts Kira!) and Badda Bing, Badda Bang
