IGNORE ALL HATERS! This is highly important.

Rating: 9/10 (4 August 2017)

Please, just watch it. Don't read comments from self acclaimed critics. This was the most suspenseful movie I've seen in a long time. Characters were portrayed perfectly well. There are always little holes here and there in Hollywood movies, don't get hung up on those.
Many reviews saying they were stupid in how they handled the contaminated lab area. There was no contamination! This movie is for smart people, not for nitwits. The crew found out the nature of the lifeform well enough to not be panic stricken about mysterious substances contaminating the lab. The movie is also set in the future. They have real holograms. Easy to assume they are better equipped to deal with biological contaminants. Things like this don't need to be explained if the viewer is knowledgeable enough. The movie only loses realism when they have to explain everything.
So just watch it without prejudice people. Thank me later.
