After the horrid, ghastly deus ex fucking machina that was Sacrifice of Angels, I had no doubt whatsoever that the Feds were going to win this gig.
Your comment about the deus ex machina nature of the episode reminded me that Ira Behr replied those criticisms.
And why shouldn't the Prophets interfere? They've sided with Bajor, and Bajor was in danger. Their Emissary, The Sisko, asked them for help. Why would they refuse?Ira Steven Behr: "I felt it was the perfect next step in the evolution of the relationship between Sisko and the Prophets that began in the pilot. Hearing people refer to it as some dopey deus ex machina is really annoying because I would think they'd give us more credit for being on the ball. We didn't have to end it like that, we chose to end it like that. Because we wanted to say that there was something going on here. And ultimately, that would lead to our finding out that Sisko is part-Prophet. They wouldn't have done this for just anyone. This was the man going out into the wilderness and demanding God to interfere, to do something for crying out loud. The corporeal characters had done so much in the episode; surely they'd earned the help of the gods."
I think Behr's defense misses the point there. Sure, there's story logic to the Prophets' intervention, but I think the criticism is that it was weak from a DRAMATIC perspective not from a story logic perspective.
It essentially ended a major arc with the wave of a magic wand. Long-term planning or not, that's lame.
I think that they should've had Sisko go into the wormhole and ask for help first, then mine the wormhole after he was unsure he'd get their help or if they said they were unconcerned about corporeal matters etc like usual.
