It's hard out there for a corpse. The Game of Thrones Cast Rates Kit Harington's dead guy acting chops

Warning: This story contains spoilers for Sunday’s season 6 premiere of Game of Thrones, "The Red Woman."

How about that action-packed season 6 premiere? At least we finally have an answer to the seemingly endless questions about Jon Snow’s fate, no matter how depressing. And now that we know Lord Snow is really dead, it’s time to move on, right?

To help make that transition a little easier for the fans mourning the loss of Snow and star Kit Harington from the show, PEOPLE asked the actor’s Game of Thrones co-stars to rate and review his performance as a corpse, which according to our poll participants, isn’t as easy as it looks. The results are mixed and hilarious.

“He’s pretty good, right?” says Sophie Turner (Sansa Stark). “I actually thought it was quite impressive. You’re not allowed to breathe, and you have to keep a vacant stare. I wouldn’t be able to do it, I thought it was pretty good.”

“I think it’s the best work he’s done in six seasons,” adds Iwan Rheon (Ramsay Bolton) with a laugh. “He doesn’t say that much anyway.”

Maisie Williams (Arya) isn’t quite as sold that the entire performance is Harington’s.

“I think they must be CGI-ing over his blinking eyes or something,” she says. “They must do because I don t know anyone, particularly outside in the cold, to be able to keep your eyes open like that would just be too much. I think they definitely CGI’d a bit. Because obviously I’ve worked with loads of dead bodies – not actual dead bodies but people playing dead bodies – and it’s not that easy, everyone struggles with it, it’s really hard when you have to keep your eyes open or stop breathing.”

Williams concedes that with or without any CGI assistance, Harington’s corpse work is excellent. “He’s doing so good, he’s nailing it,” she says. “We should’ve killed him earlier.”

“It’s very very subtle, very subtle work,” says John Bradley (Samwell Tarley). “It’s not an easy thing to do.”

His co-star Hannah Murray (Gilly) agrees. “It’s actually really really hard. Whenever I’ve been dead, the not-blinking thing is a nightmare,” she says. “It’s much trickier than it should be, it’s not a nice little lie-down.”

“I die in everything except this, and I’m still no good at it,” continues Bradley. “I can appreciate that work from a unique standpoint. In a kind of cheeky way, you see enough of Kit dead in the first episode to justify his presence in Belfast for a while. You know what I mean? ‘Oh that’s why he was in Belfast all this time, he worked, you do see him as a corpse quite a lot and when you see his name in the opening credits as well, people are going, ‘Hmm. Corpse.'”

Liam Cunningham (Sir Davos) and Tom Wlaschiha (Jaqen H’ghar) also approve of Harington’s methods.

“He gives good corpse,” says Cunningham. “When you’ve got a head of hair, that’s all you need for Kit, lying down looking gorgeous, beautiful head of hair, what else do you need?”

“My friend who was with me at the premiere, three minutes into the episode he grabbed my hand and he said the corpse’s hand was moving,” says Wlaschiha. “I didn’t see it. He said his hand was moving, the corpse’s hand was moving.”

“Really? Well it f—ing shouldn’t have been,” replies Cunningham. “I think it might’ve been wishful thinking.”

Or is it?
