^Yeah, I like the grimey look too.
But I have some cheap sets where the transfer is terrible because segements of the original films reels warped away over time and there's dead spaces.
With a lot of these HK sets a home entertainment company just clears out a defunct studio's vaults or buy in bulk from a private collector and release as-is.
Too much time and money to be wasted remastering and repairing some of these lesser known joints.
Especially if they may or may not infringe on international copyrights.
How can one lose everything when one has nothing to lose???
