Well the reviewer seems to believe 1.85:1 is the correct aspect ratio because of Warner's involvement. This is somewhat doubtful but in any event all things being equal 1.66:1 would be MORE open then 1.85:1 not less. So if anything 1.85:1 would be the tightest. Since they have the unmatted full aperture to work from there's really no excuse for this. There's some comparisons with the Warner DVD here: http://monsterkidclassichorrorforum...-OF-FRANKENSTEIN-bd-UK-on-October-15th?page=2 It looks like they were simply haphazard in their 1.66:1 placement and that's probably why they felt the need to go 1.37:1. It looks like the 1.37:1 has more top and bottom but less left and right compared to the 1.66:1 they've done. Since the transfers are otherwise nearly identical it looks like both were modifications of a much larger original transfer. That's not so unusual however. At least with this fans could feasibly create their own correctly framed release from the 1.37:1 transfer. Devil Rides Out fans are not so fortunate.
