Blu-rays that exceeded or failed to live up to your expectations

[Nostromo]

I do a lot of research before I buy, but I have to admit, there were a few pleasant surprises. All of these looked even better than I expected:

-Halloween (Carpenter version)
-The Thing
-Identity
-Underworld
-Underworld: Evolution
-Escape From New York

The only minor disappointments:

-Terminator 2: Judgment Day (Not Skynet edition)
-Terminator 3: Rise of the Machines

Neither of the Terminator movies looked as good as I'd expected them to -- a little soft for my tastes. Can't speak for the sound quality or extras for any of these, as it's been a long time since I've watched them. But I definitely remember the PQ or lack thereof.
