I admit that I’m curious as to the new score. Did they not have a copy of the original score? Did it not originally have a purpose-written score?
That said, I honestly am not bothered all that much about it having a new score. Except for notably big-budget features, it wasn’t uncommon for silent films to be accompanied by whatever music the accompanists decided fit best, so it’s hard to say that a new score is somehow a betrayal of the original. But I’m always interested in the why.
