As long as a developer doesn't get hold of it and turn it into luxury flats, despite its listed status.
I think that this is not so clear cut for me. An arthouse-style cinema with small bar would be delightful (just call me Captain Gentrification), but I would not put up too much resistance to its conversion into flats. The appeal to businesses is limited due the building's construction as a cinema -- I have only once been into the 'Spoons and found it a bit dark and definitely lacking feng shui.
The worst option would be for it to stand empty and slowly degrade as a building: "I'm in Forest Hill, yeah, so go past the ugly looking rusty bridge, up the hill with all the cars and lorries queueing to get through the lights at the huge junction -- watch out for the pedestrians running across the road on the hill to avoid the infrequent crossing signal and for pedestrians who are spilling out from the tiny road island -- then look opposite the money shops, before Ferfect Chicken; yeah, outside the huge derelict building."
