The 4K release is fine, it’s the audio which I have issue with. Replaced foley for a lot of sounds. It’s the main reason why I haven’t sold the BDs of Batman (1989) and Batman Returns. All would be needed is color correcting of it to possibly appear similar to the BD or a 35mm print, and the original cinema audio track. I barely even watch the 4K of both Tim Burton Batman films due to what I and Venny typed.
Wonder if the OG cinema audio was on the Laserdisc at all, let alone the BD. I’m not knowledgable about this, even though I did see this in cinemas in 1989 when I was 10, of course I wouldn’t remember the sound mix.
