Assuming you're a fan of the film the 30th anniversary Blu is worth the money. I've got the original Blu ray release and this release is clearly superior. Still grainy but less so and more natural looking. Better colour saturation, sharper and better detail.I'm surprised to find no further discussion of the new BD on this site; what do folk think of it? In fact, despite trawling numerous reviews and forums, I can't find anyone directly comparing the old and new releases. As a guideline, here's the Caps-a-holic comparison.
It's clear that while the previous version had DNR and sharpening applied, it wasn't in the same league as the Predator débâcle. Meanwhile, the new Highlander transfer looks almost like a raw scan, comparitively speaking, and often appears to be as overly grainy, dark and lacking in detail as the first Predator BD.
