Better than most b-movie sci-fi. I went to this movie expecting another "Species." Despite the hacked plot, tired gimmicks, and so many cliche'd characters "gun-ho general" etc.... This movie works on a certain level. The special effects were dazzling and breathtaking.
The movie obviously doesn't take itself too seriously and because of that, its a treat to watch. If you love action movies, then I believe you'd appreciate the subtle campiness of the film. They even recycled the old LA ravine that has been used in countless car chases. It gleefully leaps through plot loopholes, trumpeting that it knows that you know whats going to happen next.
