That is exactly what it is supposed to be. Think of it like The Twilight Zone, every story is different but they all exist in a world that is distinct and unnatural.

I think JJ Abrams finally came up with a good way of explaining it to people: "It’s like Cloverfield is the amusement park, and each of these movies is a different ride in that park."
