How bad is it? It has an IMDB rating of 1.8 (out of 10).
Should you see it? No.
Someone somewhere said this was so bad it was funny, but it's just bad. After hundreds of years, a creature awakens underground and starts attacking women. It's a bad rubber suit and some poor CGI that lets it move through solid ground. You've seen this before if you've seen any monster movie and you've seen it done better. You don't care about the victims, you don't care about the monster (why exactly did it awaken and why is it attacking?) and you will check your watch frequently, as it is very dull.
