If you want to avoid any spoiler, stop reading now. Personally I advice go watch the movie, it deserves to be experienced.

My thoughts on Gravity:

When I first approached the theatre I feared Gravity could fall prey of a forced horror-driven story or become tarnished by constant action sequences seen in first person from the helmet of Sandra Bullock and George Clooney.
The first lines that open the movie don't really make me think otherwise, but serve as a good premise for letting we earthlings, still attached to our planets, understand the implication of approaching an environment so hostile and difficult to explore and survive in.
I was also conflicted about having Clooney portraying an astronaut. I had seen him acting in a sci-fi movie previously, in Solaris, and while I loved the acting in that movie I always thought Clooney was too peculiar to be a successful actor in every movie he stars in, at least for me.
Well, I was ultimately happy with Sandra Bullock and George Clooney starring in this film, so much that I think Robert Downey Jr. and Angelina Jolie, or any other actor, would not have accomplished giving the same emotions the duo did. And Ed Harris being the control voice is the final touch of homage from director Alfonso Cuarón to Space Movies.

I felt terribly at home, for some reason, while watching the Earth I was in from above, overlooking the astronauts doing their job on the Hubble telescope. The shots are majestic, but also slow in shifting, which helps giving us the sensation of actually being there. In fact, the whole movie makes you fell like you have a front-row seat to admire a disaster happening and evolving.
The story is thin yet effective, and personally left a lot of questions unanswered, like the possible bad aftermath for some places on Earth possibly striken by the debrises.
Gravity plays everything on the Kessler Syndrome, and the movie's 3D effects are there to entertain the spectator and help feel like being actually there, living the disaster with the two protagonists, from the beginning to the end. There are some scientific accuracies, and while there are also pretty evident inaccuracies that some people interested in space may notice, it seems churlish to point them out, and admittedly the movie wouldn't even exist without those.
Some scenes made me cringe more than I thought, especially one of the most dramatic, where simply pulling one string could have made the story go in an entirely different way, a bit like it happens in Brian De Palma's Mission to Mars; another time was when Bullock, apparently able to relax for some minutes before returning to the disasters raging outside, is partially used as a space eye-candy with no Thermoregulator-suit and diaper underneath, but admittedly the scene is played to portray the whole humanity symbolically in the vacuity and peril space has to offer.

The film also manages to shift from dramatic moments to scenes that are cheerful and full of hope, only to let you realize moments later how alone you actually are in a place where no one can hear you anymore. Involving the spectator emotionally serves once again to give the feeling of being there and experiencing the same emotions and hardships Dr. Ryan Stone, portrayed by Bullock, is undergoing. And just like her, we start having fear, hope, sadness, up to the final scene, where symbolically we are reborn in the mixture of water and soil our planet is made of.
I don't think this was thought as an aspirational movie, but it does give awareness of various factors regarding exploration and the beauty of humanity's different yet similar cultures, although this last part is subtle. If you can, go watch it: it's an experience that sets good qualities for future movies set in space, post-production effects all serve to immerge you in the movie and enjoy it at its best, and last but not least, it's how close you can get at the moment to be 600km above Earth and admire its Auroras and its silent yet constant motion, surrounded by stars, briefly making peace with yourself and part of your past, like Dr. Ryan Stone, whom we accompany the whole time, does.
