I didn't call it glorious.

I don't support Dany's claim to the throne. She wants power for power's sake. Tyrion said as much back in season 5 -- if she really cared about making a difference in the world, she would have stayed in Essos.

The only reason people celebrate her coming to Westeros is because we want to see her interact with the main cast and the overarching threat. As the audience, we know she will likely (or, rather, definitely per the leaks) have a role to play in defeating the White Walkers, but show Dany doesn't know that (yet). She wants to be Queen because she thinks she deserves it for her name.

Dany is not really fit to rule. The only way she has ever solved a problem in the show is by using her dragons or her otherworldly fire immunity. (Even in the Dracarys scene, which is my all time favorite Dany scene, she relies on her dragon.) That's not a good precedent, and I think we'll see that in the books (and probably in episode 4 of this season). A pacifist like GRRM wouldn't include the equivalent of nukes in the story and not make them inherently dangerous.
