Managed to catch this in IMAX and highly recommend if you are going to see it to catch it on a big screen.
However it is very derivative and if you have watched a few sci-fi films you will know exactly where this is heading. I won't give away which films it is mainly derivative of as this would spoil the story. But there is a line of dialogue within the first five minutes which tells you exactly what is coming.
It's a shame it cant be more original as it is still very entertaining and I certainly enjoyed it. All the cast are great. and the world that has been created is well realised (Glad they used real locations as it shows). It's a shame Tom Cruise can't get past the fact that he is Tom Cruise as he essentially plays the same role as always but he is good. Great score as well which is a fusion of Hans Zimmer, Daft Punk and Vangelis.
