Not for everyone and not for every occasion. If you're looking for action, save this for later. If you want to see a realistic take on space exploration and its mental implications, it's time to watch this.
Realism is the keyword for this film. It doesn't try to convince the viewers with effects or stunts but rather in the way that you could for a brief while really feel you're in space. The director, Eric Hayden's father has been working on the Galileo probe that went to Jupiter which probably had its contribution to this film's script. The whole design of the ship and the mission is very realistic and it'd be quite close to the actual way we would go to Europa if we ever would.
Without going into spoilers, there is another level going on in the film. More human. Again the characters are realistic and they act like a well trained astronauts would. But as the events unfold, the mental evolution of the main character becomes analogous with the craft's journey both in space and fate.
There's a hint of third level on the movie which probably means I have to watch this movie again. It's not just the craft or the man inside who's making the journey but us, as human beings collectively.
