Funny, I thought they tried to do the "Ulysses-Courier" relationship with Miraak-Dovahkiin.
It's kind of embarassing really, especially since they have to resort to retconning Alessia and the established lore in general, as well as ripping off Morrowind again (more straightforward that Shivering Isles) in order to make things do with their new content.
I want and will play it, but I don't have a good feeling about this DLC.
EDIT:
I mean, wanting to rain nukes on the NCR was pretty much comic levels of stupid evil, as well, but the motivation made it interesting. How do you know something like this won't be the case for Miraak?
Because Obsidian has more talented writers than Bethesda. Maybe except for Kirkbride, but the guy was basically out after Morrowind.
And even if they are creative with their writing, it shows mainly in lore and books - conversations never were the forte of TES, and dialogue battles like Lonesome Road or Deus Ex HR that are necessary for it are simply not happening.
