What parents should know: I think Gravity is a beautifully done film, but there are several things you should take note of. The overall plot is highly intense and stressful, and that might be too much for young viewers to handle (especially in 3D). One scene is really violent (it's not too much, but it's graphic and obviously noticeable), and there is a bit of bad language every now and then (some of which is pretty bad for smaller kids). The stress and drama can really attract you, however, and Sandra Bullock is usually an amazing actor. Some of the MUSIC, surprisingly, adds to suspense, and startled me a little bit, and the total silence of the first scene kind of freaked me out. If you like drama, action, and awesome actors (even with all that stuff I said), Gravity is the movie for you! What kids should know: The movie itself shocked me, amazed me, kept me on the edge of my seat, and partially scared me. Sci-fi isn't my average genre, but I love dramas too. Gravity is both! The one scene I mentioned in the other part of this review might disturb younger viewers, and if you haven't seen a drama film before, the overall intensity might be too much for you. However, if you have, then see this right away! I honestly think it's awesome in 3D, but that might not work if you get a headache from it! :D What I like about it: Almost everything! This is a powerful film about never giving up, no matter how horrible the circumstances may be. The visual/special effects are breath-taking, and I started crying at the end.........that was how happy I was! If I had a rating for this movie, it would be: PG-13 for strongly emotional thematic material throughout, one scene involving violence, some stressful situations, and strong language.
