This review will contain a HUGE and unavoidable spoiler, so if you intend to see the film (you fool!) and don't want to know why that would be a bad idea, then please do not continue reading any further.
Alright, let's perform a thought experiment: I want you to imagine that you are writing the plot to a film. The movie is an Alien clone about a nasty tentacled monster, which rampages through a spaceship, killing all the crew members in a particularly gruesome fashion. Now, it is at this point that your mind turns to the question of how to end the story. If you were to make a list of all the conceivable conclusions you could present the viewers with, and order this list of possible endings with the best at the top, and the worst down at the bottom, then I think that it is fair to say that the "alien converts to Christianity and decides to help the crew" idea would be pretty far down on the list. And yet, that is exactly what the makers of this film opted for. Seriously. The creature's last words to two remaining crew members before they are tearfully separated? "I will always remember you. Goodbye."
Aside from the so-awful-you'd-swear-they-were-joking ending, the film is also hindered by lousy set designs, awful acting, and a general lack of anything above average. A complete waste of time.
A couple of bits of trivia: the theme to the film was sung by Stefanie Christopherson, who, I believe, did the voice of Daphne in the old Scooby Doo series. Also, according to the credits, this film was shot entirely in space. I'm glad that somebody is having fun with this thing.
