I watched Pirates in DLP.
IMHO, brightness was great, but that's the biggest advantage. The added brightness really made the image pop.
However, the lower resolution was easily noticable. It was easy to see the pixelation in the white sand, and other high APL scenes.
Also, black levels were higher than on a good analog system. Because of this, some of the shadow detail was lost too.
Personally, I think this is not the way to go with Pirates. There's SO much dark material in this movie, that there's some loss of realism. This noticably lower the level of immersiveness of the viewing experience.
The brightness does make the surreal quality of the ************************ scene pretty impressive, but I think that doesn't make up for the deficiencies.
****** I don't want to give away any of the movie.
