This is not exactly what we would call a good movie, just an entertainment one. Just because its story doesn't offer itself more. One of its aspects is however good: the visual scenes, effeects and images of the space ship interior with all its gadgets, machines, appliances and instruments. The movie story and plot is very simple and can be summed up like that: a scientist space ship with a six member crew travels in the space near Mars when it meets a living creature that invades the ship and attacks its crew kiling even four of them. That creature begins to be a small cell but it keeps growing and growing till it becomes a strange monster full of aggressive tentacles. The whole movie projection is the fight of the crew with that being until only two survivors remain in the end coming back to Earth. It keeps you entertained around two hours or so.
