Some loyalty missions were definitely incomplete methinks. Now whoever's streaming the game probably won't get the best end.

I have concerns about the last episode writing aside not a fan that

Oh yeah... Forgot about that

Took Anakin years to snap though. Started having issues in Ep 2. Dany just snapped willy nilly because "need to shock the audience".

I dunno, she's roasted a fair amount of people. Been quite ruthless too. Hasn't the show spanned several years by this point as well?

Personally I'm more concerned with how rushed and forced her madness felt more than anything else.

Then she wasn't listening to Tyrion's speech in the previous episode:

"I know you don't care about your people. Why should you? They hate you and you hate them."

To reiterate what I was saying earlier, I still think what “development” we got in relation to Daenerys' madness was absolutely atrocious. So much that it felt like D&D were writing a baby's first fallen hero from a (bad) JRPG or something.

But basically, from the hack writing we got, Daenerys seemed to “snap” from a combination all the shit she's been through so far (being married off as meat, having a stillborn baby, losing two of her dragons who replaced said baby in a way for her, etc etc) and Jon Snow's superior claim which pretty much invalidates all the work she's spent on trying to reclaim the throne.

Seeing her best friend Missandei die would have been one of the last straws for her, and when she heard the bells of King's Landing signifying the surrender, and viewing (for the first time) most of this city and the Red Keep that represents everything she's lost in her life, she decides to burn it all down.

Now you could definitely say this is awfully executed, and it was. Daenerys essentially “seemed” to go nuts for almost no reason at all, and god damn did Varys' death happen too fast in the most illogical manner. But I don't necessarily think the elements for her madness weren't there, they've just been gutted the same way as the rest of the plot.

If we ever see the books complete, maybe they'll handle this whole thing better. We can hope, anyway.

The show runners, in their wisdom, has now stated that she snapped just like that. "Like Targaryens do". 

They don't understand the source material.

Even the Mad King took years to go fully crazy. Dany snapped in a minute.
