FTFY. Maybe wasting the audience's time with go nowhere plots for the last 3 seasons wasn't a great idea?
Btw its possible to believe both of those sentences at once.
Yeah, here's the thing that makes literally no sense about what we've seen this season:
-The Iron Fleet stuff is basically nonsense at this point. When you look at a map, has to sail past Dragonstone to get to King's Landing. But it's possible they'd sail about 100 miles away from the island and not come into contact with anyone... you can only see a few miles out over open water, depending on your elevation. The presumed order of events is Dany lands on Dragonstone -> Euron arrives at KL's sailing -> Dan'y fleet leaves for Sunspear -> Euron's fleet chases them down somehow. The most plausible way this goes down is that he has his fleet sitting at Massey's Hook waiting to see which way everyone goes (with some carefully placed, very fast scout ships and Westeros' infallible ravens) and then moves to intercept Yara.
-What makes no sense is that Greyworm and Yara would presumably be sailing together all the way down to Dorne as that's the only way to get to Casterly Rock. Even if they left at different times, the order of events gets quite murky because...
-Getting from there back to King's Landing and then off to Casterly Rock in time to sink Greyworm's fleet is actually impossible. You're talking about thousands of miles and months of travel... so unless Greyworm left weeks
before Yara (which would make no sense given what the show presented... or it's possible that Yara was on her way
back from Dorne when they got intercepted?) they both would've run into Euron's fleet. If he left week's
after Yara then they would've already known that Yara's fleet got sunk and never would've sent them. In short:
1. If they left same time (what is implied) they would've both hit Euron's fleet.
2. If Greyworm left first, he'd have thousands of miles of head start on Euron and be uncatchable.
3. If Greyworm left later, it wouldn't make sense as Yara's fleet would've already been burned and the timeline would be off by months.
4. If Euron got Yara's fleet on the way back, they'd have the same problem as #2.
... most annoyingly, they could've avoided all of this by saying "Euron left part of his fleet behind in the Iron Islands to wait for the Unsullied to show up"... but instead they show Euron's boat specifically.
-The Tyrell's were regarded as (currently) the most powerful house in Westeros with the most food, men, and gold. And the castle falls in one day to an army no siege required. Makes literally no sense.
Lazy writing and storytelling.
