It's about rights ....... Bride of Dracula was already shown recently on BBC4, and "Dawn" was the only Romero film available ........
Meanwhile, Suspiria keeps cropping up on film4, and Driller Killer and Little Shop were on Showtime .......
John Carpenter? Well, Halloween established a genre, and The Thing is good (truer to original than Howard Hawkes) ..... and The Fog was wonderfully atmospheric (but crap ending, I must admit).
