As much as I think it should’ve gone to dreamworks, I’m not willing to completely write-off illumination just yet. If Nintendo is working closely with them they can make it clear that the film needs to have some substance and meaning. Illumination is capable of making meaningful films like the first despicable me, but it seems like they just don’t like making them very often.
I also wonder what part of the timeline they’ll use. BOTW/TOTK are selling well, but they’re in a very odd part of the timeline. If they want to appeal to the masses and hit most of the traditional Zelda beats found in most games (dungeons, Triforce, Ganon), they should set the movie a little further back in the timeline.
