Gravity starts with some great visual experiences, especially in 3D, and the first half of the film maintains interest and excitement in what is basically a very simple story involving the two main characters. The second half of this tale is neither believable, interesting nor realistic in any shape or form. Veteran astronaut, George Clooney appears far too cool during a major catastrophe in his attempt to save the damsel in distress, a medical engineer but inexperienced astronaut played by Sandra Bullock. Early on, local critical reviews rated very highly, some referring to a modern day classic of 2001: A Space Odyssey status. I don't think so. An enjoyable film at 90 minutes in length, but very average in its entire context. Somewhat of a disappointment after all the early hype and expectations.
