Even before watching this flick, I was actually really intrigued by the whole concept. On top of that, it was pretty neat to finally see Bruce Willis turning up in a SF flick so I was quite eager to check out the damned thing. Of course, since it was a Hollywood production, I wasn't expecting anything mind-blowing but, eventually, it was still pretty entertaining after all. First of all, there was a nice cast (Bruce Willis, Radha Mitchell, Rosamund Pike, James Cromwell, Ving Rhames). However, to be honest, even though Bruce Willis was decent enough, I don't think he added much to the whole thing and any other star could have done the job. Anyway, I still really enjoyed the concept, even if it seemed rather unbelievable that 98% of the world population could afford such a device which seemed to be rather pricy. At least, it did provide some food for thought. Unfortunately, instead of developing the implications of such a world, the makers got stuck between some endless talks explaining what was going and some even less interesting generic action scenes. Still, even though it turned out to be nothing really mind-blowing, it was a well made and entertaining SF flick and it is definitely worth a look, especially if you like the genre.
