I didn't feel like that at all and it surprises me anyone did. Do you have the same problem when you see people walk in real life?

No, and other high-fps video I've watched (all on much smaller screens, though) hasn't had that effect. I've wondered if the sensation was generated by some combination of 3D + 48fps + viewing angle. Or maybe something to do with the post-processing particular to that film. My wife reported the same effect—people walking with a casual gait but seemingly slightly sped up. Also affected other movements of people and objects, but walking was the most noticeable. The level of distraction it induced was similar to when audio and video are slightly out of sync (though, to be clear, they were not, that's just the kind of constant low-level distraction in caused)

We saw the second one in 24fps 2d (we mostly avoid 3D because we rarely care enough about it to pay extra, but it was the only way to see the first one in 48fps) because we both hated the first one's presentation so much, so I don't know whether we'd have experienced it in that one.

I had the same impression of "speed-walking", and I saw it in 48fps 2D. It almost felt as if the projection was lagging sometimes and then sped up the film to catch up or something, it was very distracting.

I've never had the same impression from TV or home movies which is 50/60 fps.

It's a widely discussed effect that tons of people have complained about, including famous directors -- so one can hardly be surprised others find it as such too.

I for one, don't like that kind of high frame rate motion -- it looks as fake as bad CGI graphics.

Was that the frame rate or just hobbits trying to keep up with Gandalf?

> My complaint about the 48fps (after going in hyped to see this Spiffy New Format) was that everyone looked like they were speed-walking all the time,

I saw all the Hobbit movies in 24fps, and—especially (at least, this is where it first really stuck firmly I in my mind as wrong) in the underground scenes in the first, but also in parts of the other two—had a similar impression.

I think it had to do with some other element of cinematography particular to that film series, though it's quite plausible that 48fps exacerbated it.

I agree. The orc chase across the rock-studded field did not look good. I found it distracting, as the higher frame rate didn't allow my eye/brain to predict their motion.
