For the "cheapened" part, it eludes me as I wrote earlier above. They spent part of the time airing an early story for an hypothetic next season when they knew it wouldn't happen. They had some hope but they could have just not spent money and air time for that, it made no sense. And they left many pending threads because of this, it could definitely have been more properly tied up.
Yeah, all the things happening on that planet just added to nothing at all.
