I felt the need to review this film because at 8.8 I feel it is being reviewed in the same class as some truly great films ... Firstly I fully understood the film and thought the idea and effects were very good as was the acting. The main issue I had with this film was that there was seemingly endless portion of it that was just full on panic drama shooting effects slo Mo's etc. Less of a rollercoaster ride more of a wall of death.. some people might like a film paced in such a way ....but I don't. I like the pace of a story to give you ups and downs.. a mix of dialogue and action... Stress and calm... Ying n Yang if you will. This film film should even out as a rating of about 7.5 imho ..which is still a good rating ...but 8.8 I really think is too high.
