This surprisingly compelling sci-fi film takes a while to set up its universe but delivers down the stretch. It's borderline whether they establish enough credibility so as to invest real emotion in to the characters and buy in to the premise

If you allow yourself to buy in to the bizarre concept of living life through android duplicates, then the film works on a few levels. It's somewhat weak on certain of those levels but raises interesting questions concerning the level of our technological dependency as we live our lives. The emotional aspect of this movie plays better thanks to a fine performance by Bruce Willis. His character's journey through this bizarre world is obviously the heart of the film and it's written and portrayed very well.
