Well Galileo and Isaac theorized about it, but last night I experienced it.

Rating: 10/10 (13 November 2013)

I really want to convey how thoroughly enjoyable this movie was, but at the same time I don't wish to gush over it. The reason being, that if anyone was reading my review with the thought of watching the film, it is possible to build something up too much and precipitate disappointment.
So no hyperbole, just a cool, clear, opinion, delivered with an almost scientific emotional detachment.
1. Ask a question, to whit, should I go and watch Gravity, the new science fiction thriller starring Sandra Bullock and George Clooney ?
2. Conduct research and make observations. Which I did, after reading up on this movie, the consensus seemed to be a favourable one. I had also observed previous efforts by the actors involved and had enjoyed them.
3. Propose a hypothesis. The theory being that it would be to my benefit to drag my TV loving backside down to the local purveyor of IMAX entertainment and watch this film.
4. Design an experiment to test this hypothesis. Plans were quickly drawn to rendezvous at 19:45 BST at the Odeon, for a screening of the entertainment.
5. Test the hypothesis. I watched the movie.
6. Collate results and draw conclusions, to support or reject you hypothesis. The results were that I had a fantastic evenings entertainment. Watching a tense, thrilling tale of two astronauts left stranded, by a terrible accident, in orbit, two hundred miles above the Earth.
I concluded that the fantastic performances given by the two leads in the piece, combined with assured and innovative direction from Alfonso Cuaron and some dizzying special effects on the IMAX screen, produced a infrequently experienced, yet palpable sensation within me, that for the purposes of this experiment I choose to call, "thrilled to bits".
I strongly suggest you conduct your own experiment, as I did, in relation to the subject matter. I feel confident you will draw the same conclusions I did.
I did notice that some people here on IMDb seemed to have drawn somewhat muddled results from their experimentation in this area. Their conclusions were tainted by perceived scientific and procedural inaccuracies within the film. Having a limited knowledge of these things, I could not hope to debate these issues on any kind of an equal footing. (SPOILER-ISH) That said, I did read a vehement "technical complaint" in relation to something (completely scientifically impossible) that occurs in a scene which is well established as a dream sequence. I'll leave you to draw your own conclusions from that.
