Remember that computer game from the 1990s called Myst? This is like that video game, puzzles, creepy atmosphere, cool sound effects, difficult to figure out. Unlike the game of Myst no one has made a walkthrough of this movie yet. I kind of liked what I saw but I understood very little of it. This isn't a terrible movie, but it is slow paced, and like mentioned by numerous others, difficult to figure out. The surface story is clear enough but the underlying mystery needs a bunch more explaining. There are a lot of good effects that are totally creepy and the ideas behind the story make it worth a watch if you are curious.
