Folks, I don't own one yet but reports are popping up all over that the 5th Element for BR used a non-clean master. Apparently dirt, dust and scratches show up. Also, sharpness is not "all that eye popping".
I read this over at AVS and a link at

"However, make no mistake, this is a good-looking picture if you're not too critical. I bet the average consumer who saw this disc up and running at their local Best Buy would probably think it was darn swell. However, I felt there were some deficiencies inherent in the source material itself that keep this one from hitting a homer, or even a solid triple. Though not as noticeable perhaps on the standard DVD releases (even the Superbit), 'The Fifth Element' looks oddly soft in HD, with a lack of detail and three-dimensionality that ranks it as not-quite-demo material in the high-def sweepstakes."
