No, it doesn't. The finest details haven't been obliterated - they were freaking
improved; It isn't brighter by a long shot; It doesn't look artificial; it looks very natural instead.
Look at
this shot. it is freakin' detailed and there isn't any kind of dirt, grain or blur.
If you're not happy with this blu-ray, no one forces you to buy it. Go back to the DvD version, if it is so much more detailed (?) and Carl Weathers' mustache doesn't look airbrushed (!).
The
Blu-Ray.com reviewer, I'm sad to say this, relied too much on the original *flawed* look of the film, and the review misses the point of Blu-Ray itself - cleaning a film to make it the highest quality possible. Predator UHE is one of the best Blu-Rays I've ever seen.
