As far as the other movies that I watched this past week:
I don't disagree with any of the placements as they are now, though considering Need for Speed and other Tier 0 quality titles, these other releases look less than stellar.
Superman: The Movie (1978) -- I might be tempted to place this in Tier 3, but I will say that several moments in the film were Tier 0 quality transfers, while the rest stayed in the Tier 3 range, but those several moments give you insight as to where it could be with a better transfer, so I see no need to move it in the Tiers.
Superman II: The Richard Donner Cut -- Wow. And not in a good way. Mostly soft, blown out contrast, just really an overall mess. Tier 4 is correct placement. While the test footage used showed softer focus and less polish, even the scenes from the theatrical cut were just mostly gross overall.
Superman Returns (2006) -- Considering Superman: The Movie's placement in the Tiers, this is obviously a better contender for PQ. However, not as much as you might think. Excessive BANDING (this looked like I watched it off of Netflix Streaming, and not on blu-ray) and an overall soft focus gives this blu a PQ not much better than the movie that came almost 30 years prior. My suspicion is that the softer focus actually makes the CGI elements blend better and that it was used intentionally. Also, it should be noticed that this movie exhibits perhaps the worst case of orange/teal that I've yet seen. The entire movie has been color timed to a muddy/dirty mess. That isn't to say that many moments of clarity in textures were evident, but too few to move it anywhere farther up and some cases may be made for moving it down (but, I'd argue that there are many moments of clarity that redeem the other shortcomings).
