I’m not a fan of Halloween in any case but I don’t mind the occasional theme week, if it is occasional. Though what with that, musicals and Blackpool the other weeks can be made to feel a bit like second-class fillers. Everything is about building up to the next theme week!
I am still campaigning (not actually) for a return to just two types of dance a show, so that we lay people can compare a few of the same type of dance.
