Why would they be? This is the internet man, they might be considered spoilers in some nursing home or something.
3 and 4 were good episodes. Glad we get to see some Bronn action.
The ambush in episode 4 by the Harpysons was kinda lame. It was what, ~8 fully armored and armed Unsullied (best infantry in the world, trained from birth, etc., etc) against maybe twice that number of peasants wearing robes and wielding a combination of knives and swords. In an enclosed space where the Unsullied could have just closed the gaps and kept them at bay forever with their spears. Instead, they get slaughtered as if they were some fresh recruits... all, of course, except the one Named Character Unsullied whose helmet Dramatically Gets Knocked Off so we can see Who's Fighting. It's like that Ninja trope. Then Selmy comes and looks cringe-worthily slow while the Sons of Harpy politely refuse to attack him from behind for the longest time. All in all, the action scenes have improved, the Selmy thing was clearly a limitation of the actor.
