It should be no surprise that a former (and still working SFX man) was at the helm of this movie. You can clearly see his handwriting or rather effects writing or whatever you want to call it. Unfortunately the script and the characters do not hold up to his effects standard. And while the movie is not bad, it's not really good either.
You get cardboard characters and story developments that are easily guessed by anyone watching the movie. It's still a neat ride overall, but never a really completely satisfying one. I don't really blame the actors too much on this, because I've seen some of them in better movies and with better performances. If the focus could have been on other things than the effects and the set pieces, there might have been a chance this movie would have gathered a larger following.
