I've found the opposite with my Darblet. It doesn't help softer or "poorer" or lower res material as much and as agreeably as it does good HD material. Typical sharpness controls add something to the picture to make it look sharper - ringing around outlines. Producing that additional light ringing around image outlines will tend to make even lower res sources look sharper, because you are adding what isn't there.
Whereas the Darblet (for the most part) simply amplifies what IS there. If there is more detail there to be seen, it makes it more visible, but it doesn't work wonders on poorer source quality IMO.
As for getting "what the film makers wanted" or a perfect reproduction of the source, my impression is that the Darblet controls, much like any other image controls, can be used subtly or too much. When I crank it up higher and higher
I do get the feeling I'm seeing an enhanced, altered image. Highlights on people's faces for instance start to take on an artificial "pushed" look that isn't there with the controls off, and which I feel certain a cinematographer would
start to object.
I saw the re-release of Bladerunner on film a while back and it was gorgeous. When I put Bladerunner on HD DVD on my JVC RS20 projector it was amazing how similar it looked to what I saw in the theater. However, on my JVC RS55 I watched it with the Darblet, probably around %50 or so. Many times the image was distinctly sharper than I saw in the theater, or viewed on my RS20 without the Darblet. In that way it did jump out as "enhanced" to me. At the same time, it really did add some "wow" to the image that was hard not to like.
I've been very appreciative of the Darblet as it seems to allow me even bigger image sizes while maintaining great image clarity.
