Of course they have better resolution, but actors shouldn’t look like wax works. Predator is a prime example of this. The early Blu-Ray release, even though it’s an MPEG 2 encode, is way better.
Yes. The second release was a DNR nightmare.
Some of my favorite Blu-ray releases are just clean 2K scans with minimal cleanup. Verhoeven’s RoboCop and Total Recall remasters look amazing. Paramount could do the same with the Trek films and most fans would be thrilled.
