I don't think you can ever really get rid of it. Like you can make it a little bit better but I feel like it's something that will always be there in a way. I have it really bad so I may be crazy/wrong.
I saw it when it first came out and didn't like it that much and then I rewatched about a year ago to see maybe if I was just too young when I first watched it, but I wasn't wrong it's not a good movie. I just found it boring.
have you seen the Babadook? what did you think? (i have had INTENSE discussions abt that movie, there is a lot of love and a lot of hate for that movie...)
