Matt Hurt’s review published on Letterboxd :
Seeing the "unrestored" version of 2001: A Space Odyssey in 70mm on the largest screen in Indiana (one of 5 theaters in the country showing it in 70mm) was by far my favorite viewing experience of this movie. This was my 5th time seeing it in a theater and my 2nd time in 70mm. This new "unrestored" version was a step up from the slightly aged 70mm print I saw in 2016. This new print was absolutely spectacular.
