I didn't find it scary, but its not a bad movie. I'm aware of the games but I don't know the detailed lore. I can tell you that watching the movie gives you the exact same feeling as if you walk in on someone playing the game and stand there and watch for awhile. Sort of a "wtf is this?" vibe. The movie tries to explain 'what' is happening, but never really explains 'how' or 'why' so its kind of "A wizard did it" sort of finish to what the trailer presents as a mystery film, which leaves you feeling like your time was wasted.
