I knew about the lack of extras for MI3 but I'm surprised that the extras for MI and MI2 are missing from the HK set, I don't think I saw anyone mention that before. It's not not a big deal, seeing as the best extra from the MI2 DVD wasn't on the Blu-ray anyway.
MI isn't outstanding, but it's great for a Paramount catalogue title. It's not a new transfer, no sir, but the new encode looks more like the HD DVD rather than the DNR infested US Blu-ray. The lossless sound is a bit flat compared to ye olde AC3 laserdisc, yet give it a bit of extra volume and it can still shake the room.
MI2 again uses the old transfer with a new encode, so expect lots of visible grain & EE, some decent fine detail though. Sound is very nice.
MI3 looks very good indeed, although it does veer into 'my first DI' territory at times, with yellow skin tones that make people look like they've got liver problems and visibly crushed blacks. The black level itself is dark and inky, but there's nada in the shadows. I remember seeing both of these issues on previous versions, so I'm pointing no fingers at the encode. Unlike before, there's no shimmering on the Vatican wall (where the van breaks down) but I did still catch a glimpse of it on the stairs in that interior shot. The lossless sound is excellent, although it's quite a lean-sounding mix so my sub was curiously subdued.
