Despite the pre release plaudits for Gravity, I approached this movie without any preconceptions although I must say that I considered cancelling the order following some of the negative reviews on Amazon...I am glad that I didn't.
I found the film quite fascinating. It's not an action or adventure but more of an intense survival roller coaster that had me hooked from start to finish. Yes I will agree that the script appears weak but in the overall concept I believe that is what was intended. The film is short but again, there is only so much you could do with two primary actors and while dialogue was typical Americana, Sandra Bullock played her roll well.
The picture quality in 3D is outstanding as are the CGI effects and the soundtrack is commensurate with the film type.
There are a number of scientific inaccuracies in the film but I didn't buy it for a science lesson. If you want a sci fi action movie then this will not appeal, if you want something a little different, give it a go.
