Its a scary movie and my description is vague its been about 10 years since i saw it but ill explain as best i can. The intro was the previous family who lived in the haunted house. They were at a long table where they were trying to get the demon or watever out of the possesed family member but it went wrong they all died. When the movie starts its about a dad and his teenage daughter and younger son. They move into a new 2 story house where the demon or watever entity is. The daughters room i believe was painted pink and she was seeing a guy her dad i dont think approved of. One day when the dad and son was gone the daughter brought the guy over without her dad permission. In the end i believe they all died and i think the dad died first and i think the son and daughter hid in the attic but ultimately were killed somehow. I dont remember any names but i hope someone knows the movie. Its an older movie probably early 2000s possibly 90s but more likely 2000s
