Enjoyed this SciFi thriller though wanted it to be longer. Creepy in some ways, but very entertaining. Notable at first is that Willis appears to be 25 years younger. Radha Mitchell is stunningly beautiful in this, but like Willis, THAT is her surrogate. Effects are first class and story line and plot pacing is good. Am biased in favor of "Robot" movies and this one delivers decently, though I prefer a darker ambiance like Blade Runner. There is something VERY redeeming about this which involves Willis and his wife, but that should remain a surprise. There is a most excellent action sequence with Radha that You will find highly entertaining. Warning: If any of your loved ones are acting strange check the back of their head for a rectangular opening.
