Of course, I'm including all three mentioned suggestions.
"So, how about The Ring? They did Ju-On already, it makes sense to do their other inspiration."
"Do they just watch the movie or do they have access to the actual tapes?"
"Go in the order you mentioned."
"If they just watch the movie itself, I think they'd just be very confused. 'Why does the lady look like me/mom/my wife?' But since this is a horror, they'd enjoy it nonetheless."
"Probably. Sadako inspired Erma after all, IIRC."
"But if it's the TAPES then things get interesting. Maybe it's just lighthearted trolling from the Williams, I mean there's a comic where Erma pulled a Sadako on her dad. If it's the tapes themselves... Sadako crawls out, only to find two ladies who look like her long lost relatives and a guy who's unfazed. Either that or Erma pulls an UNO reverse card on her by crawling INSIDE."
"It can also be someone else, let's say Sidney, is watching the tapes. Then what looks like Sadako crawls out. Nope! It's just Erma coming over to play and watch Warrior Unicorn Princess."
"Looks like most of our ideas involves a reference to the television scene."
"WELL, the television scene is quite famous and is also one of the family's gimmicks."
