LOL! That’s great! My father complains more about the Gravity movie being inaccurate. When I visit, I do not watch space related movies with him... not if I want to enjoy them.
I actually like "Gravity", although I couldn't help but notice a rather glaring mistake in the plot. As pointed out in TV Tropes:
The space shuttle, the International Space Station, and the Chinese Tiangong are all within spitting distance of each other, despite really being in vastly differing orbits. The Tiangong is "100 miles" (in one line; "100 kilometers" in another) from the ISS, a figure which evidently stays stable in this film. Of course, if the movie was following the real-life distances and orbits however, Stone would have never survived. Cuarón stated in an interview that an early draft of the script did try to work with the fact the HST, ISS, and Tiangong were in different orbits in reality, but it ended up with half the movie being the characters explaining orbital mechanics, so the decision was made to put them all in the same orbit for plot convenience.
