There are only 15 theaters in the world showing TFA in the "native" format for which it was shot - 70mm 2D.
I was fortunate enough to see a showing of it last Friday. The Indiana State Museum Imax (
http://www.imax.com/imax-indiana-state-museum-oo) has it until mid January. Although, there aren't many good seats left for hardly any of the showings if anyone wants to make a road trip.
I'm not a big fan of IMAX's aspect ratio as it's too confining from your peripheral vision. I am a big fan of 70mm (or 65mm) resolution. One thing I really dislike is the ever increasing gimmick of main stream movies having "sequences" filmed in IMAX and then switching in an out of a different aspect ratio. It's way to jarring for me when watching a movie. The Star Wars films are Cinemascope... end of story.
TFA's IMAX sequence is the escape from Jakku and it is visually impressive. While the rest of the film gets IMAX's digital upconversion process to create the 70mm print, the Jakku sequence benefits from the native resolution. JJ's framing of this sequence looks natural enough as it simply expands the top and bottom of the frame. It allows some unique views of gunnery station on the Falcon. The real treat of course of the 2D 70mm print is simply the huge screen with the dedicated lamp for IMAX horsepower to drive it along with the benefits of the IMAX projection system for celluloid to keep gate judder minimized.
Watching TFA the other day on the big screen brought back fond memories from my childhood. My first viewing of The Empire Strikes Back was on 70mm and I also got to see Return of the Jedi in that format as well.
For any diehard Star Wars fan, I would recommend seeking out one of the 15 theaters with a real 70mm 2D print. Unfortunately, since there is only 15 of them, the marketing engine that is the current IMAX regime steers the masses to one of the LieMAX digital screens.
The good news is that one of the most impactful things that Uncle George accomplished before his retirement is that through Lucasfilm, he really did raise the ante for average cinema experience that the majority of us get to see at our local multiplex. The THX program began as providing a standard of quality for cinema sights and sounds. Through it digital cinema sound got accelerated. The argument that is digital cameras will forever be debatable; but, nobody can argue that the introduction of the digital projector has significantly raised the bar for the average consumer watching a movie. Unless you are a big enough nerd to know which movie theaters actually care about the condition of their projection equipment (lamps, registration, cleanliness of the print, etc.), most of us can walk into any multiplex these days with a digital projector and be guaranteed a better experience than the previous generation.
I took my niece to see TFA on Saturday and the digital projector was lacking a bit of shadow detail and resolution from my Thursday 70mm 2D viewing; but, there is no debate that it was close and that the Atmos sound was better.
Although the golden days of cinema are behind us... it's still a great time to be had by going to the big screen.
