Not top 5. Too cheesy. The deus ex machina with the army of the Vale to save the day was expected, but Jon, Tormund, and WunWun all coming together like the 3 musketeers and charging the castle alone was cringe worthy. And then suddenly even though their infantry had been mostly wiped out, dozens of archers appear to subdue Winterfell. And of course it's Ramsay that puts the final arrow in WunWun. Seriously?
It was like the battle of Cannae but written by an adolescent.
So it wasn't in any way shape or form a deus ex machina
And feck off with your moaning. It was epic and fun and I loved every minute of it. It's a fantasy series, it's supposed to be romantic and illogical at times.
