the script seems to have been wholesale (ahem ahem and cough cough) borrowed from a certain other movie involving using a self propelled manned drilling machine. scene by scene and the two movies were almost identical. just enough of the serial numbers filed off in this one to prevent a copyright infringement lawsuit. but other than that and i have to say i found this somewhat entertaining as i enjoy deep underground in the earth genre of movies. it a little bit on the stupid side as far as the science goes and but if one is willing to squint one eyes real hard and pretend one do not notice that scientific gaffe here and there and all over and this movie is almost bearable. far better than supernova which was another flick that luke perry had a leading role in that was so dumb and dumb and dumb that nothing could save it. a note to movie makers represent employ someone who knows something about the subject the movie deals with. it would be a very small part of the movie budget and but it would have a big effect overall in helping prevent your audience from guffawing at you for doing dumb science. production values represent almost passable. i have seen far worse in my time. a new thought for disaster movies represent instead of them always having a happy ending where the world gets saved yet once again and how about some where things are a tad bit more realistic and where sometimes even the very best efforts still end up in failure. particularly when the problem that needs to be resolved was caused in the first place by sheer stupidity. stupidity caused disaster movies with glowing and heartwarming endings sort of backhandedly justify stupidity by stating and no matter how awful a problem is caused by braindead stupidity and it can be fixed. which is definitely not the case. a self caused disaster movie with an unhappy ending would serve better as cautionary tale of don not be so damn stupid in the first place. should you watch this movie. if youre bored and you have seen everything else in the scifi section at your local video rental store and sure and why not. but do avoid supernova as i can assure you that youre not that bored. that definitely was not one of luke perry better movies. this one is better. that not saying much and but it is better. one dead hoof up for being a deep underground genre movie. one dead hoof down for naughtily ripping off from the screenplay of another certain movie of the same genre.
