content: - Some good special effects involving the spaceship, the weapons disintegrating their targets, the vast subterranean Krell complex.- A simple but compelling story- The performance of Walter Pidgeon- Anne Francis (hubba hubba)There are a few minor problems with the film, like the goofy ship's cook character, but they don't detract much from this very enjoyable, landmark science fiction film.(By the way -- some other reviewers have noted the debt owed this movie by subsequent sci-fi franchises such as Star Trek. This is undoubtedly true; if you've seen the original Star Trek pilot "The Cage", you can see the similarities in the space vessels, uniforms, weapons, etc. -- not that they look exactly the same, but that they have the same feel as those in Forbidden Planet).
