Yes she was mad a long time ago. remember when she hung the masters. She never showed mercy.
The final, it was a final. Did I love it. No. Was it good, well it was ok. It seemed a bit boring then again this season was not top notch. Was it what they intended as mentioned above, absolutely not. The books were not finished so they took over. It's not the same writing.
The problem is that all the conflicts were just too rushed to resolve. It all happened so fast that it's like what just happened? The Knight King defeated already? Kings Landing crushed, already? Dani killed, already?
What's the deal with the Night Watch? There is no more White Walkers and the Wildlings are no longer a threat. Is there even a need for the Night Watch anymore?
Still it was one of the best shows ever. Even if the last season was not as good as the others and if they stretched it out and milked it we would have gotten fed up and moved on. At least it ended.
