I do not know about drone shows.. arguments posted here are good on ratio, like polluting and the type of ppls involved. But I must confess that all the drone shows I have seen I found quite plain to be honest. Fireworks do still offer more for the senses. Beside the visual, the sound of fireworks is so much more diverse then only the bzzzz of a group bees. The sound delay from fireworks gives much more tension/excitement. The smell is something I also like somehow. All the senses get a bit more to handle which is interesting to watch/listen/smell fireworks.

I think drone shows could learn from that and be way better by combining drones with picoprojectors or combining a lasershow with smoke blasts. Or combine also some fireworks with drones. Maybe place subwoofers on drones and create a sound pallet. There is enough combinations to think of as long as there is some spark.

Aside the droneshow firework show, I totally agree on blocking the egocentric people that blast away with fireworks during a random night or towards people
