Sorry, but I completely disagree and I can only imagine its been a while since you watched the DVD. This transfer is far superior, the grain is kept to a minimum and there are no signs of DNR. In truth I really enjoyed it and it looks pretty much like I thought it would.
To be honest though, you don't even tell us why its so bad, just that you don't think it looks any better than DVD, and that could be down to the size of your TV set.
Finally, it doesn't spell disaster for the future of Bluray at all. Or did stuff like this not happen on DVD every other week? Even if your not impressed with this transfer, most major releases are superb and well worth owning the format for. So even if your disappointed with Ran, lets not blow it up out of proportion.
