This dramatization of what is essentially the Russian equivalent to "Apollo 13" is one of the best real life space 'adventures' made. Excellent production qualities, good script and acting and completely plausible effects.
As a thriller, it's drier than "Gravity", but fans of "Apollo 13" should be very pleased and satisfied.
Edit: I started writing this about half-way through. When the movie finished I upped the rating another notch, even as the god-awful credits song was playing. My only criticism is that whoever chose the music was selling something else.
