Daenerys actually becoming Queen and then fucking it up? Interesting. Definitely needed a full season to play out. I have a horrible suspicion, though, that the whole point of this is to have her die in sight of the Iron Throne without ever having sat on it, because Deep Symbolism or something.The person on the throne should be someone we like and is a good ruler, that would have made Dany trying to conquer westeros actually morally ambiguous, the people wouldn't support her, the other kingdoms wouldn't support her and she would go apeshit and burn things down.
IMO it would work better that way.
