Outstanding acting what makes this movie more chilling

Rating: 9/10 (31 October 2012)

I lost count of how many times i have seen this movie, It loses some impact, if watch too often,
I Can see why a lot people find this movie scary (Also can see why some people don't find that scary)
, it dose have some scary moment in this movie, there some scenes that will creepy you out, Like head spin (Which I found little funny) and stab-ing scenes, some may find hard to watch.
The make up effect makes were good, she looked scary as hell.
Linda Blair who played Regan MacNeil was absolutely amazing in this movie, the way she acted in this movie, felt like it actually happened to her, made it so real.
Over the years there as be so many Exorcist movies, not one of them made look as realistic as this movie,
