Oldham used to mount a big civic firework display in the park. That was dropped several years ago- round about the beginning of the millennium- and no-one seems to have complained- or even noticed.
Bonfire Night has been edged out by Halloween. Ghosts and witches instead of Catholic terrorists with Van Dyck beards. It's understandable. Ghosts and witches are perennially fascinating; most of us stopped being frightened of pointy-bearded Catholics a while ago.
I did wonder whether V For Vendetta might reverse the trend. Apparently not. Alan Moore's novel is a period piece- which could be why the film didn't do that well. No contemporary freedom fighter would think of wearing a Guy Fawkes mask. Apart from anything else, he wouldn't be able to find a shop to sell him one.
