The new transfer overdoes it with the timing, but the idea is at least in the right place....if this were a fan edit and not a supposed restoration.
There is a reason why restorations are not timed to match IB prints. They are NOT a true reference as each print can vary from each lab in each country.
And this disc overdoes it. It has the warm feel of the Italian transfers of the first two films and then goes way beyond that in the digital domain. It's as if you sat there and cooked the over-bright MGM extended 35mm for hours upon hours.
And what did they use for 4K scanning? The restored MGM source?, the o-neg?, the MGM held source, presumably the United Artists held neg? or an Italian source?
Who knows? where's the information? Why doesn't somebody involved say, hey guys-here's what we did and with what.
Here we get the usual MGM mono downmix of a 5.1 re-purposed track. And unlike the old discs where the Italian mono was at least intact, we get the restored German mono instead. It at least sounds very good, but unfortunately being another foreign dub has different levels of effects, music and dialogue throughout.
Back to the freaking drawing board. WTF goes on at MGM/Fox when they do all this stuff? I'd be far happier with battered 35mm from the archive scanned at 2K and dumped on a BD-50.
