The first scene is like Gravity

It's a terrible scene. The rogue satellite comes drifting along like a car doing 100 km/h rather than the 11,000 km/h it should be doing (closing speed even higher when combined with the Russian satellite already moving), unless the Russian satellite was actually overtaking it.

Then Superman comes along with his cape flapping like there is wind in space. He also speaks at the open door to space and can be heard by the cosmonauts.

Still a fun film though, with some good serious tones mixed in for good balance.
