Jaws only worries me on the audio. The video portion looks great if not exactly 1975 era coloring. The 7.1 new mix is wholly unnecessary and even in their restoration video you can see the severely clipped audio tracks being used. This film has one of those mono mixes that is so damn well done that I hate to see any kind of remix.
S. Spielberg said:
There’s two fronts, on any successful conversion, to Imax resolution, which is significantly clearer and sharper, with much more depth and fidelity than the movie appeared in theaters in 1981. So the first tier is where you take the DI [digital intermediate] and you enhance the resolution to Imax resolution. The second tier is that the sound is significantly different. They take the [audio] stems that we gave them, and they put them through their 12,000 watts of digital surround sound, and it’s a totally uncompressed experience.
Still it's 4K digitally blown up to IMAX size, so not what it could be, and to top that off, the new restoration loses some of the look of the original photography in my eyes. It's a bit too sharp, too clear, and contrast/color very high. This may be from seeing Raiders on video for too long, but still it shouldn't be that much.
The new mix sounded identical to the DVD mix, but very unimpressive in the theater. (this may have been coming from Dolby Digital off a print) IMAx sound to me is never impressive, being jacked up to be extremely boomy in action sequences and then dropping off to almost nothing for dialogue scenes with little to no surround seperation. TDKR was extremely disappointing on this front. You could hear the projector hum at times louder than the actors. (Not that that's a bad thing.)
BTW on the new 35mm print the snake reflection was gone again, but Marion's still present. Original cliff shot intact, and I'm not sure but the rod/stick thing may be gone from the boulder chase.
What worries me is if this will start a trend towards more releases this way, because I don't look forward to having tickets all costs $18+. Plus I still have serious reservations about the design and structure of the IMAX theater. It feels really awkward.
I don't hate on Spielberg, but he hasn't made anything really worthwhile since Empire of the Sun which is sad.
