Well, I dislike HFR as much as the next guy, but the reason he's abandoning it is because of the ecosystemic/economic context within the movie industry which doesn't want to take visual risks with their production investment, not because Ang personally doesn't like HFR.
Aside from that, never been sure why he's enamored with the look. I've read his rationale, but it still doesn't jibe. HFR pulls movies way too close to visual "reality" and narrative film are stories. Make 'em ups. Pretend. The nature of 24p's look is a huge asset.
