The movie is not bad. Good drama and sci-fi. But maybe they could've add some more ingredients to make it more spicy. I can't call it a slow movie like some reviews suggest, overall it's pretty nice film. But I have to say it's a little overrated. I mean this is no way near as good as Interstellar (2014). But still a very good try, they just missed to achieve the tag of "WOW".
