++. Yes, and not your standard Linux distro in design, never mind the hurdle of understanding Nix expressions and functional programming language. However, once tweaked, deployment on multiple machines is straightforward.
Another horror favorite: Don't Look Now (1973), directed by Nicolas Roeg, starring Julie Christie and Donald Sutherland. Set in Venice, it concerns a couple recovering from the accidental death of their very young daughter. Roeg uses the color red as a signature throughout the film: things are not always what they seem.
One of my favorites, one I feel is hugely underrated, Michael Wadleigh's 1981 Wolfen, which is not about werewolves, but ecological displacement, loss of habitat from urban development (among other issues), and not terrorism --- a conclusion initially drawn by the police --- but territory. With Albert Finney, Diane Venora, Gregory Hines, Edward James Olmos, and Tom Noonan. Its release in theaters was eclipsed by “The Howling” and “An American Werewolf in London”, but Wolfen is not merely a horror movie, but an intelligent one, ahead of its time IMHO. The confrontation atop the Manhattan Bridge between Finney and Olmos (see below, not a spoiler), which still makes my knees weak, involves no stunt doubles. The film also has beautiful dog sequences, imaginative cimenatography, and yes, some gore.
