I guess it's not so much your criticism itself but the way you have put it forward.Robert Wheeler wrote: I really don't see why having a point of view, substantiating it, and then insisting the criticism is relevant and incisive causes such indignation.
The discussion about the correct speed of "Metropolis" is a pretty old one around here and probably a lot of other places and regularly surfaces time and again. I have agreed with you initially at least so far that I believe 24fps is wrong, especially as I've seen the reconstructed film theatrically at a slower speed with live accompaniment of the Huppertz score with full orchestra at a time BEFORE Transit released their original disc. It was performed even by the same orchestra and I believe the same conductor who did the recording for the current disc; I'm pretty sure it wasn't 16fps though, but something around 20fps, as the performance lasted around 140 or 145 min and had natural-looking movement. Hence my argument that FWMS themselves were not sure about the correct speed, at least at the beginning. Where does that lead us to? You believe that anything above 18fps is wrong, I believe that 20fps would be just right, and both of us agree that 24fps (or, godforbid, 28fps) is wrong. All this is basically a matter of 'how does it feel for you', and you're entitled to have your opinion as much as anyone else.
We won't come to a conclusion, anyway, as Koerber's points are certainly valid from his perspective, although I believe that he places too much emphasis on that premiere screening about which we don't know much (at least we don't know the reasons why it was projected that fast and whether Lang agreed with this or not). My belief that 20 fps is correct can only be backed up by comparing the flow of the images to the other films by Lang which are invariably transferred at 20fps to disc, and all look perfect to me. So if Lang made all his other silents at 20fps, even those two he made AFTER "Metropolis", I'd be surprised if he chose another speed for just this one film and then reverted back to a slower speed for his next two films.
Criticizing the MoC transfer, if there are any problems with it, is allright of course. It has been done with other films by MoC as well around here, with no bad feelings raised. But what is needed is substantiation: either post screen caps of those moments you think are problematic, or point to them by giving the exact time on the disc so everyone can check and compare for themselves. But please no ad hominem arguments and sweeping generalizations.
