Pretty good, but not the best Park has to offer
I'm a bit tired to elaborate much right now, but I will say this is a pretty good movie that you should definitely watch if you liked Chan-wook Park's prior films.
The Handmaiden looks and sounds fantastic, is rich with character backstory, loaded with eroticism and has plenty of confidence - enough to not back out from some almost pornographic sex scenes between the two main actresses. But I feel like it needed to offer more to be the best Korean movie this year; I've already seen The Wailing and I think it does almost everything better than The Handmaiden does (no matter the different genres). I just wanted to point out that Park is a certain type of director who tends to prefer style over substance or get lost in lurid details of the script; much like Tarantino. Don't get me wrong, I do love most of his filmography but The Handmaiden "amplified" the importance of sudden twists and nudity so much that I felt like I was watching someone's sexual fantasy wrapped up in a neat film noir package.
Overall, I gave it a 7 because I expected more, although it kept me seated for the whole time. What did you think of the movie?
Oh, and definitely check out The Wailing if you still haven't. My thoughts keep frequently coming back to it because it's just so *beep* great! :)
