Say Yes

Oh, it's one of 'em murderous hitchhikers again, only this time, he's from South Korea.
Well, usually very reliable Patrick Galloway more or less raves about the qualities of Say Yes in his book Asia Shock, but I don't see very much to rave about here. Sure, it's well acted, slick like every single South Korean film I've seen, nicely paced, brutal etc, but it doesn't get to me at all. Most of the time I felt myself watching in abstract appreciation mode. "Oh, that's supposed to be creepy". "This is a very disturbing face Hitchie makes there". "Ah, a sudden and brutal outburst of unpredictable violence". Immersion? Not so much.
The original Hitcher is still the Evil Hitchhiker Movie of choice.
