S08E04 of Games of Thrones might be remembered for the wrong reasons.
After the previous episode saw many people unimpressed with the gloomy lighting, Monday's episode also left some fans feeling bitter.

Fans noticed a takeaway cup from the coffee giant Starbucks on a table in the particular scene.
Now, the show's producers have responded with a joke on Twitter, admitting there had been a mistake.
It's estimated the coffee cup gaffe is said to have generated more than $1 million worth of free publicity for Starbucks.
But while Starbucks might have been jumping for joy at the gaffe, it's brewed up quite a storm among fans online.
"You're telling me they had TWO YEARS to put together a decent show and they couldn't even spot the goddamn Starbucks cup in Winterfell??!?!" one Twitter user said.
"I would like some giant's milk with my latte, thanks," another joked.
