Yeah, maybe I just don't need to go that deep when it comes to exorcism movies because I had a grand old time with this one! I have to say, I thought the actors who played the afflicted did a great job acting possessed. They, that crawly shadow thing, & that column of "OMFG-I-truly-hope-THAT-thing-doesn't-exist!" at the end were all pretty creepy! Think about it...a writer actually envisioned that thing...had it bouncing around in their brain pan! Yeesh! No thank you!

Other reviewers mentioned the lack of character development &/background stories, but I thought enough was done to make me care about them, or at least want to continue watching them. The actors were talented enough to carry the story without needing to rely heavily on history. Would I have liked to learn more about Ji Shin's (Woo Do Hwan's) backstory, & how he came to be the HOTTEST paragon of evil in Seoul? Absolutely, but I didn't feel the plot required it in order for me to feel satisfied. I think it's safe to assume he'd been through some s**t, tho.

Park Seo Joon's athleticism was a joy to watch. He did a great job overall. My only beef with his role was his insistence that he didn't believe in a god, which was addressed. As an atheist, myself, I can't really get pissed off at something in which I don't believe, & it was very clear Yong Hoo was furious! I mean, I get why they wrote his character like that. This was a Good v. Evil/God v. Devil movie, after all. At least they didn't resort to the "Well, He believes in YOU, Son" zinger.

Bottom line, I was thoroughly entertained!
