'What you leave behind' was kind of disjointed IMHO. First there was the resolution to the War, which was fairly predictable, although the stuff on Cardassia with Kira etc was good. Then there was the Sisko/Dukat/Pah'wraiths bit which was kind of abrubt given the huge build up. And then the flash-backs etc, which was kind of nice (except for leaving out Jadzia).
If there had been a little more tension in the war story and spent a little more time on the Pah'wraith plot, it could have been great IMHO.
