The ending to the Dominion war, which makes up the bulk of this 2-part series finale, is excellent - from the Cardassian rise up (nice to portray them positively in the end) to the final battles, it was a very satisfying conclusion to the main storyline. The final departures of characters, with Worf becoming an ambassador, Odo returning to his people and O'Brien going back to Earth, were also bittersweet, and it felt like saying goodbye to good friends.
The only part that didn't work well in this final episode was the same part that had been going wrong for a very long time now, and it is the Prophets / Bajor storyline. Here at the end, we continue to have the most iconic science fiction franchise shoot its own leg with what transcends the - albeit blurry - borders of trekobabble and goes straight into magic. Godlike aliens like the prophets were nothing new in the Star Trek universe, but their evil enemies called Pa-wraiths spelled trouble from the start - culminating to a plot where they are released from a cave through a magical incantation found in a forbidden tome (which released its secrets after spilling blood on it), and possess Gul Dukat. Sisko pulls a Gollum, jumps with him in the raging fires and....well, clearly, the magic book burned, so the evil wraiths were banished back to hell, and Sisko was saved by the prophets and trasnferred to the wormhole. It is a sad and nonsensical affair, but not enough to take away from the main story. However, it is a total waste of what was, along with Garak, the most interesting recurring character of the show. Gul Dukat was a fascinating character as a narcissistic war criminal, with lots of layers to his portrayal. This last season's transformation into a possessed Satanist made the last confrontation with him anticlimactic.
