I would have like it more sci-fi than "horror". We need more optimistic movies.But then again, I knew it wouldn't be a relaxing movie, and I should have guessed it was going to be hard to watch.Otherwise, nice actors, beginning of the movie was cool, and the idea of life on Mars was cool.

The concept is interesting, but there is too much gore. The scenes with Calvin inserting its tentacles and killing its victim from within were too graphic (even for someone who watches Game of Thrones) and there were too many of them.

Predictable and not much of a story line. How can you kill a main character and star of the show within the first 15 minutes? It was just a monster going around killing everyone.. worst movie I've seen in a long time.

Predictable, to much like gravity meets alien. Glad i didnt pay for this movie.
