Oldboy. A lot of energy. It’s a revenge flick and a couple other genres, too. I’m not thrilled with the ending and various revelations, but I can’t complain when the journey there is so good. At the very least, watch the corridor fight scene. Ridiculous, but just real enough that it doesn’t feel like a total put-on. And how about that soundtrack? I watched on Tyler Cowen’s recommendation. I’ll have to look up some more good Korean movies, as I know basically nothing.
