This was one of the best sci-fi alien movies I have watched in a while. I loved the imagery and the story telling. It was scary, thrilling, and suspenseful. Not sure why people are complaining about the absence of dialogues? we have audiobooks for that. Not ALL movies need to have dialogue and a story does not necessarily need spoken words to be portrayed. Dever's performance was really good too and was believable. It is not easy for everyone to fake emotions like that for the cameras. Just my honest opinion.
