I found it quite compelling. It’s common for sci-fi films to violate our current understanding of physics, but to just explain it away as a new discovery in physics (think star trek’s warp drive). Others like Star Wars don’t even bother to explain anything about how their ships fly, enter atmospheres, etc.

What was unique about Gravity was that it was sci-if but set it our universe and in our contemporary time period. It at least tried to operate within the constraints of current inventory of space hardware. You are non-space-enthusiast it was amazing.

Yeah. Wall-E had more realistic use of a fire extinguisher to move in space.
