I actually feel like Mara’s concept is something new. Because everyone knows about sleep paralysis, but no one would’ve imagined something like this related to sleep paralysis. So I think it was a great try of delivering a new concept. But it wasn’t that scary.BTW I expected a different ending like if Kate could find a way to stop the power of this demon after the investigations, it would’ve been great. Anyway it’s a great try. We expect part 2 of this movie with a great ending
