Once you get used to what the picture is really supposed to look like you're going to find yourself walking into big box stores aghast at how the sets are configured. Neon green football fields, blinding white levels, and colors so saturated they obscure any detail.
Collin, I noticed this right away on the first uncalibrated HD set I saw. Blinding. On the other hand, I can now see the texture and nuances on the playing field grass on my set.
Admittedly if you've gotten used to your set's punchiness proper reproduction might take some getting used to, but you'll soon realize that everything looks more accurate and consistently good.
No question about that. You do have to spend time with it. The set is now on a level I didn't think possible.
A test you can try once you get your set calibrated is to pay attention to the PQ and color fidelity next time you see a film in the theater and try to see how close it matches your memory when it comes out on DVD.
I haven't done direct comparisons between theater and HD-DVD, but from watching HD-DVD, I can't complain.
Absolutely film like.
