Why movies look weird at 48fps, and games are better at 60fps
This article is detailed and scientific.However, anecdotally speaking, the concern I have with evaluating high-frame rate in film is that we have very little context—most of us have only ever seen Peter Jackson's Hobbit films in HFR.  In other words, I have never seen how other directors' work would be affected by HFR.Speaking exclusively about the Hobbit series in HFR, I too observed an uncanny valley that traditional films intrinsically avoid with their low frame rate.  The Hobbit films felt more like a play than a film.  A play with elaborate stage effects, but a play nonetheless.In fact, my chief criticism of Jackson's directing with HFR is that the feeling of watching a play is amplified by how he mixes the sound and directs his extras.  The extras routinely just mumble nonsense in the background, leaving only the character you're intended to be focused on speaking clearly.  It's the same thing you see in a play when there is background dialog, and it's completely unnatural.  You find yourself sometimes distracted by the characters in the background and realizing they're not actually doing anything meaningful or having real conversations.  For example, in the most recent film, I found myself more distracted by the unnatural audio in early scenes (such as the beach scene) than the HFR video.Combine that with the poor acting by the minor characters in the first 45 minutes of the recent film and I think HFR gets a bad rap in large part because the Hobbit films alone are our point of reference.
