This is a great flick for people who are irritated by sub-plots because there are none. There is nothing resembling reality found anywhere in this movie, so it makes for excellent escapism, which we all need now and then. Since all the characters stay together, it is easy to follow along, so you can turn your brain off, it won't be needed. Since it's all about the ship, acting wasn't necessary. You can bet that movies like this toll the bell for the careers of Russell and Dreyfus. I felt pity for them as actors, and hope they can rebound. The movie is shorter than most, so there will be minimum impact on your life. You will remember nothing about it soon after exposure.
