Now, I have seen worse than this, but, this was pretty dumb. Giant spiders, spitting lava?! How dumb can these movies get? I just don't see the entertainment in this movie. And, the people being chased by the spiders, aren't even scared! They act scared, but aren't really scared. Sure the special effects and visual effects are good, but the storyline sucks. And then there's the acting. Now I've seen worse acting on the Syfy channel, but this movie's actors still need to work on it. Not to mention the ending. The ending was worse than the rest of the movie. It could have been so much better. So, with all that said, this movie is a true embarrassment to Syfy and to all the other production companies that were involved. The problems here are poor storyline, bleak dialogue, bad acting, and just plain dumbness.
