The ending was really lame.
I was expecting Daenerys to AT LEAST make some kind of a rousing speech but no, nothing.
That was really her plan? To kill their leaders in a fire, walk out of it, and expect 100k Dothraki to spontaneously fall on their knees and declare her their new boss?
The way it'd more likely have went:
"Wow, how is she not burned? That's weird."
"True- wait, did she just kill all of our Dear Leaders with the fire?"
"I wonder if she's as resistant to getting her neck snapped in half as she is to fire. Let's find out!"
But no, instead aaaaaaaaallll the Dothraki just fall on their knees, even though maybe 15% of them even saw what was going on.
As far as I remember, the Dothraki don't particularly worship fire. Then at least it'd make SOME sense, if they were like massive R'hllor worshippers. But they're not. To my/our knowledge, they have no "whosoever isn't touched by fire is The Great Prophet and shall be obeyed in all things" legend. Their religion is centered around horses.
All in all, a really weak plot device that doesn't make sense, just to give Daenerys her next great army. At this point, Daenerys scenes just make me cringe because she's basically Mary Sue.
