I enjoyed the blood lust honestly
I now see Dany and Greyworm's actions as a reflection of how much of the audience (myself included) has felt the last 3 episodes.
Getting to the end, the endgame, the final of the long journey to only find that it wasn't satisfying at all.
Watching the piss poor defense of Winterfell. The "Character kind of forgot" things. Removal or complete walk back of characters we spent years investing in. The obvious plot armor.
Whats left when all that happens and only Michael Bay remains??? Rage!!!
And for Dany and Greyworm... it's also rage.
