"Passengers", a movie about space travel (with just 2 actors on screen for the most part), takes your imagination wild into the endless realms of space.
The conceptualization of space travel is the best part of this science fiction.
How do you travel to a planet that is many hundred years away without aging and dying on the way? There lies the main plot.
The gigantic spaceship has been imagined and brought on screen so well. Although there is the usual heroism and romance, you can still admire the movie for the creative story-line of space travel.
Like someone said, "Passengers" is a mix of "Gravity", "Interstellar" and "Cast Away".
