Not a bad film. At times a little creepy and always suspenseful. The deliberate attempt to re-create that awe and wonder of early Spielberg blockbusters (think ET) is a little heavy-handed but works. The special effects and some action sequences feel loose. But all in all this is affecting and effective. One underground shot is brilliant. Stay for the super 8 footage that plays during the credits: this is perhaps the film's best part.
