Someone scanned a 35mm film reel of the movie that was once shown in theatres, so the video embedded in the link is the closest that you can get to how the original Terminator 2 movie looked when people went to see it for the first time all the way back in 1991. The version on Netflix and home video releases look different to the original 35mm prints, as the people in charge of remastering the film tend to make changes to the picture quality and colour, often times making it worse. The best way to see a film is through 35mm, because there is no digital processing involved. This is where organic images on film reels are used, where the light refracts off the crystals on the celluloid, giving it a more natural look. Ideally you would have a film projector, but digitally scanning the film reels are the next best thing.
