First the technical aspects of this film. The acting was very well done. The cinematography and camera use,lighting, editing...all on Hollywood big budget level. The score/sound effects as well. The story , as others have already mentioned, very similar to "The Game" with Michael Douglas (Just happens to be one of my all time favorite thriller movies ever) So, the PREMISE is not new. But I don't hold it against a film. Was there plot holes? Yes. I tend to be analytical and notice things like that, but as I've grown older I have also learned to quiet my brain to suspend belief enough to enjoy what the point is, when it is presented. (I don't nit pik as much)
What is NEW, compared to the movie "The Game", is this is a little more personal with less action. A little more in depth with the character facing his pre conceived ideas about himself and the world around him. In my opinion, that's always an interesting process to watch. I was also tickled to see the humor/satire injected into this movie, that "The Game" didn't have. The ending is super. And scared the crap outta me.
