An interesting case for sci-fi fans and a missed opportunity for the director, having a generally decent cast, a sufficient budget and a story, let's say 'not overused enough for that time'. The totally obvious Alien rip-off is technically surprisingly well executed and pleases with almost top notch set designs and very good creature effects. Now that all this didn't make an absolutely satisfying, or actually even really good sci-fi movie can be blamed on the lack of tight pacing in the script, occasionally bad editing or I guess generally the rather inconsistent lead of George P. Cosmatos, resulting uncalled-for moments of amateur filmmaking entering into a movie otherwise to be taken serious. These then start accumulating and gradually getting out of control as the movie gains speed (among others resulting conversations on the subjects of popcorn and puzzles) and then ultimately explode into a 5 minute orgy of total C-Movie crap, actually even added after the anyways forgettable climax of the movie (how the hell did that happen by the way?). Otherwise, we can say, that the first 2/3rd of the movie is pretty okay, not counting a few minor downers and then gradually messes up in the finale. In the end you decide weather it was worth watching or not. Though for genre fans I guess this is absolutely obligatory.
