I think Basterds was shot that way. I recently saw V for Vendetta on Blu-ray and the video was great, but not spectacular, however the sound was pitiful. I think a lot of this has to do with the way they are converting it for Blu-ray. It is a newish format and I think that soon they will get it right every time.
Some movies are on the second remaster, and these are doing away with the mistakes of the first generation. Full Metal Jacket and The Fifth Element are two examples. I've seen what I believe are the first masters of both and they looked excellent, I can't imagine how they could get better. However, once I see them, I'm sure I will be blown away again.
These days I end up going for the Blu-ray first and if I have to, I'll slum with the DVD. There really is a huge difference to me. I don't buy many though, so I am usually constrained to the rental shelf, luckily a local shop here has around 6-700 for rent, and more out each week.
My only complaint with Blu-ray is the same most had with DVD when it first came out. They won't transfer most films to this next generation of disc. I love foreign films and there are some making it to Blu-ray, but I have a feeling that most will not. I hope I am wrong.
I do agree, there is a big difference in quality from movies to actual HD camera filming. The films/documentaries in true HD are breathtaking.
I've never been an upgrade for the sake of upgrading kind of guy, but these days I want more out of my HT. I have had my Sammy 550 series Plasma 50" for 10 months and I am ready to move up to the 850 series as soon as I can. Audio can be very subjective, video not as much, at least for me.
