In Time - Andrew Niccol made maybe the best Sci-fi movie of the 90's (Gattaca), which unfortunately compares to Matrix or Terminator as pig's trotters by Pierre Koffmann compare to KFC. Having learned from the experience In Time is an easier watch. With great IMO concept (time left to live replaces all currency) it follows it as a good sci fi would. The plotline revolves around huge inequalities - the poor live day to day, sometimes no longer than 25 years, the rich live forever. Movie works because as always in a well done sci fi it is an allegory of the present.
The weakest element here would be Justin Timberlake, but even he is still OKish.
4/5
