Good but could've been better

Rating: 7/10 (25 March 2017)

I hadn't even heard about this movie until my girlfriend made me watch its trailer just a few days ago before it came to theaters in Turkey. After watching the trailer, we decided to take our chance.
Along with many positive things about the movie, such as its atmosphere, consistency, "Calvin" and so on, I kept thinking like "Yeah, it's good but could've been better" many times during the movie. Its music, tension and rhythm and casting could've been better, but the movie is still good enough to watch at a movie theater. The director tries to add some depth to the characters, but it somewhat fails, too, due to its not-so-long running time probably.
In conclusion, if you are into sci-fi movies, you should totally give it a chance. The director is rather young for a director and the movie at least doesn't have any logical flaws or inconsistencies like most of sci-fi movies.
