The death scenes are usually extravagant. Sometimes they may make you cry. It's one of those instances where you go, "NO, NO, NO, DON'T DO IT," and it's an excellent plot device heightening the mood in a horror film (or book). You have to ask yourself then: what are the best ones we've seen? Well, here's a list:
The Lonely Death of Jordy Verrill (Creepshow)
The Mass Train Leap (Suicide Club)
The Terminator's Molten Death (Terminator II: Judgment Day)
Technically, we shouldn't even qualify this as a suicide, because the T-800 is just a machine. However, in the realm of this story, it definitely applies given the fact that the Terminator can't self-detonate. Think of this as Terminator euthanasia. An assisted suicide, if you will. And what a tearjerker.... Suicides aren't just scary. They're emotional, too!
The Suicidal Plague (The Happening)
Say what you want about Shyamalan's strange outing with "The Happening" (and a lot of his other films), but the scene of several people practically tossing themselves off a building was quite chilling and bizarre. Sometimes suicide really is bizarre, hence why this film about mass suicides due to a strange type of pollen in the air definitely makes the grade.
Keanu Reeves and Charlize Theron (Devil's Advocate)
And lastly.... This doozie of a film. I saved this one for last, because you get two suicides in the film, and their scenes are utterly glorious. Gory. Emotional. All of it rolled into one. Clearly any list requires this fanatical demonic Christian thriller of a mindf*ck for obvious reason. The downward spiral and throat tearing of Charlize Theron as Keanu freaks in horror only to have the film end in a beautiful finale to him smiling at the fact that he has "free will" and shoots himself in the head. Al Pacino (SATAN) didn't like it very much. What a way to go!
