We know that marketing can sell products that are less than good but how trailers, reviews and previews have managed to convince so many people that this is a great movie is beyond my comprehension. This movie is dire. The story is weak, unengaging and unbelievable. The characters evoke no pathos and empathy in the viewer resulting in an experience that is woefully dissatisfying. Sandra Bullock, supposedly a trained astronaut, begins by complaining about feeling nauseous in space and rapidly moves to ongoing pleas for help as she is thrown around in space. Whilst this would probably be a frightful experience George Clooney fortunately manages to stay calm and gradually secure some kind of rescue for the distressed damsel. He should have thought of himself! OK, so we have impressive 3D visuals but after 10 minutes of extreme depth of field anyone whose thoughts are drifting from the less than riveting storyline is likely to begin contemplating how 3D movies don't actually simulate how our vision works. We are selective in what we focus on and 3D films offer us visual information that is frequently irrelevant. Save the entrance fee and cost of the spectacles and go see a good story told well e.g. Blue Jasmine. Gravity isn't even a B movie.
