Extraterrestrial signals are found on three locations in the solar system: Titan, Triton, and Eris. The US government dispatches a top flight astronaut to discover the sources of the signal. The mission will take roughly 10 years. This auspicious premise was enough to keep me interested during the 100 minute run time.
As others have pointed out, at times it feels like mashup of 2001, Contact, and Interstellar, though unfortunately it doesn't have that aura of awe inspiring discovery that those other films did. For example when our protagonist sets foot on Titan, the first moonplanet to be reached by humanity besides Earth and the Moon, it's a very ho hum affair. You'd think anyone who did make such a journey and land on that celestial body would be overcome by, or at least grasp, the magnitude of the moment, much as Neil Armstrong did when he took his first steps on the Moon. Instead the protagonist merely treks onward to the source of the signal without any emotion or pause to take in what he is actually doing. This was extremely disappointing and hard to believe that this was overlooked by the writers.
While the low budget special effects were fine, the dialogue and characters were not. All of the characters behave rashly and inexplicably, unlike the calculating intelligence we saw from humans in 2001. The character Becker records a message divulging some personal information he was not supposed to, then towards the end of that message realizes his error in divulging the information, but sends it anyways. What?
In spite of all that, the movie is still enjoyable if you're a sci-fan or one who is particularly interested in SETI or the work of Carl Sagan.
