The effects and graphics are very good which makes the movie more scary for some people. Also the storyline was very organized and it really takes the audience into everything. Even the exorcist scenes we're very well executed and believable. Also the story had some interesting turns which suprised me.
Also I think the best part was the acting. I enjoyed the acting of the cast members (both of the main and the support) really really much.

There was too much blood and gore for a 15+ movie. Also the movie tried to scare the audience with a little too much jumpscares. The whole exorcist theme can be very unrealistic.
But all in one I think it's worth watching.
