My two pennorth for what it's worth (very little).
It doesn't really matter, at least as far as I can see, what the film's like.
It could be good, bad, indifferent. Authentic, contrived, truly derivative or not. The music might be correct and of the period or it might not.
It doesn't really matter.
The film is obviously being made in the hope of capturing the imagination of an audience and therefore making (here comes that taboo word) profit.
I am sure that the filmmakers will make every effort to try and capture the "spirit" of the times, but obviously their primary concern will be making a film that has a good story and has good visual impact.
I understand the negativity of other folks on the list, having our precious scene cast into the limelight. But I think that in the final analysis it will, beyond a little bluster, have very little impact on the scene.
Anyway back to lurk mode.
