"Fox made the unconventional choice of opting for an MPEG-2 encode on a single layer Blu-ray disc, a bad habit I thought they'd dropped months ago. Even with as challenging as Predator's grainy visuals can be, I didn't spot any compression artifacting, but I can't help but wonder if a more efficient codec would've resulted in at least a marginally better looking presentation or freed up enough space to carry over all of the DVD's extras."

Conclusion:Predatormay be my all-time favorite action flick, but this Blu-ray disc feels like microwaved leftovers with a Ruth's Chris pricetag. A single layer disc with an MPEG-2 encode that's probably been collecting dust for ages"
Fox has repackaged and reissued Predatoron DVD over and over again, and there's really not any doubt in my mind that a much more decked-out Blu-ray edition isn't any more than a couple of years off. As much as I love the movie, I'd recommend renting this initial Blu-ray release"
