It’s always a pity to see a movie with a nice idea, which hasn’t been fully developed.  “Unknown” is one such movie.  It started off pretty good, but there was just not enough suspense and acting to pull it through.  It became boring and unimportant pretty soon, but the idea shined through the whole movie.  I wish there was more work done on this but now it’s a bit too late.  Maybe someone else will pick it up and redo.
