The problem with fireworks these days, as Mark and Horza have just said, is that they are way louder, way bigger, and way more powerful than they used to me.
They are certainly far removed from the little boxes we used to buy for the back garden when I was growing up, these are very powerful explosives, which is a worry.
The other problem is that anyone seems to be able to buy these huge fireworks now, so where I think they used to be for displays only, joe public can now buy pretty much anything on the internet, which is a worry.
