If you look only surface and estethichs.

Otherwise plot is actually quite hollow.

Astronauts with that kinda mental problems wouldn't probably get to space at all.

Not even talking about how she failed all simulator flights.

It isn't even close to scientifical accuracy.

Space just don't work like that.

Hubble and space stations aren't on same orbits at all. So manuver to other space station from ISS and Hubble would be extremely difficult and it would require much more fuel and time.

If you know even little bit about orbital mechanics this movie would be pretty much impossible.

If space trash goes on different orbit that you orbit you wouldn't even see it at all.

Why did Russia even shoot their satellite?

I wanted to like more it but as space nerd it little bit impossible.

Overall it isn't that good movie actually.
