Cops & Robbers' master is awful, probably real HD but with absolutely no restoration work performed, faded colors and poor details overall.
I've seen (and reviewed) several Spectrum releases and while they're absolutely commandable for the movies they're releasing and the extras coming with them, they clearly don't filter their choices regarding the HD masters' quality. Some actually barely look HD at all (
The Dragon Fighter for instance), often making me wonder the technical reason for putting those out on BD and not just DVD.
Devil Hunters is relatively OK visually, but the soundtrack is a nightmare. It's extremely muffled and shallow, like some of those Bruce Lee tracks that sound like they were recorded underwater.
The Saviour also looks HD, but seems like a very old HD master full of sharpening and heavily over-saturated and with its contrast excessively boosted, and limited details overall.
Story of Woo Viet and
Boat People are clearly from dated HD masters (though they look HD at least).
Angel Terminator 2 looks very good, like a recent 2K work, but Angel Terminator 1 looks like a dated HD master again.
The Terrorizers is similar to Angel Terminator 1, Woo Viet and Boat People.
I don't doubt all those upgrade over how they were released before but these are still very limited way too often.
Their Bride with White Hair package is nice, though a tad expensive considering the 2 additionnal movies clearly are extra movies. The 1st movie uses a new 4K restoration like looks quite neat (though possibly a tad DNRed), but the sequel re-uses the awful old master with however a new color-grading (it still looks quite bad), and the 3rd movie is the recent White Haired Witch of Lunar Kingdom, which is only provided in 2D (no 3D version) and in 2.0 (not even a 5.1 track) because Spectrum haven't been able to obtain the 3D version and 5.1 tracks from the right-holder. For those who can understand French, it does pack almost 3hrs of extras !
Be aware that most of those BDs are 1080i50.
Out of their upcoming/most recent releases, only Lonely Fifteen is announced to be sourced from a new 2K restoration, so I don't have my hopes very high about the HD presentations of the other releases.
