Appreciate the thought waves! Would take a braver man than I to contact the studios (tried that once on another matter, and was met with stony silence... even Google-translated the message. Not to say a non-reaction should be expected every time, but I wouldn't have much faith in the power of one letter getting read by who-knows-whom).
As for slipping through the cracks, yes, once in a while that could be possible; although in this case, I know from my notes that GVG-149 was definitely up and around once. (Its inclusion was definitely removed, as has been the case with other examples. Yet in the case of GVG-149... why?) And there are too many examples now of missing cases, whereas in the past knowing the movie would come up through a DMM search would feel so cozy and contented.
We have to get used to the reality of DMM no longer being the comprehensive giant it once was, but given the way searches used to be, so hard not to get the heart to sink with each new increasing example of a no-show.
