This is not a perfect movie. It is also nowhere near the worst of all time. It is a low budget horror movie, and not a bad one. Hollywood dumps worse than this in theaters every January and late August.

In all seriousness, I think I could have filmed a better movie with my phone in the back yard, given enough time. Where to start........ I mean, there's really nothing redeemable about this movie. The plot is dumb. Why not just drop a bomb into the mine shaft and nuke all the monsters in it? Dumb. As for the monsters that are in the mine. - you never learn anything about them except for some scribbles on a piece of paper shown on the screen for about 5 seconds. Seriously. That's it. You only actually SEE the monsters in the movie for about 10 seconds in the entire movie. Seriously. That's it. Save yourself the frustration of finishing the movie and saying to yourself, "Why did I waste my time with that?" Horrible.

Something is down there in the ground, and with dishonest causes for being there where the ground smokes and the mud is warm, really rams this group of five. but as in every 3rd monster movie the monster is barely visible, a blurry outline and a flysnappersflowers mouth piece is the only you can see.and apart from loads of groans and growels, and dissapearing mighty men that should have a CO detector instead of a CO2 detector. the guiding ''lola'' caracter seems like and sound like a toomb raider caracter, and the continous darkness keeps the secrets very well hidden till you cant figure out whats what. so productionwise it has many glitches, and a very troublesome daylight logistic nightmare. the darkfilming is so bad, so what is in the dark stays secretly there in the dark forever. so go out and find yourself an abandoned coal mine pit and make a copycat outta this.you just have to be cruel and sinister and dumbfoundly curious in the acts, its really nothing more. it started of with a 6, ended up with a weak 4 thinks the grumpy old man. its a shallow story, poor caracter development and the filming is a nightmare

I wanted to like this movie, but it was just ok. The acting is solid and some great atmospheric moments. The story is not all too original but still intriguing. Where the movie fails for me is in two spots. First, yes I know it is mostly at night, but parts are just too dark for the human eye. Second, the whole film is based around the monsters that we hardly get to see enough of. Worth a watch but keep your expectations low.

Ok its not ground braking or anything but its not has bad has most people here say it is. We do see the creatures... and they are scary. Its your normal creature feature. No there is no explanation of why they do this, where they come from etc.... The cast is good they are not annoying all beautiful airheads, but nerdy like science guys. All in all an OK horror movie to past time that is not going to win any Oscars.

Wow someone got paid actual money to make this film. Ok so you cant afford special effects but at least have a script that wasnt wrtten by a 12 year old. What a terrible film, bad acting, bad dialogue, bad story bad everything, bad, bad, bad.

While the film certainly isn't Oscar worthy, it's still an entertaining film. Some pretty good practical creature effects and with a variety of designs makes the monsters seem pretty original in my book. I praise the scenery because they did an amazing job recreating the feel of Centralia here. A decent amount of shots have some style to them and keep it from being too monotonous. Wouldn't mind a sequel honestly. Acting was alright, though Will Payton did an amazing job as always so that's a plus. Turn off your brain for an hour and a half and enjoy.

There is nothing redeeming about this film. Cast is unlikeable, silly plot and most of it's shot in darkness. A real stinker.

1) No real plot 2) No real character development 3) Really dark and blurry 4) Makes no sense. So why didn't they just contact the government? And if they went all out to protect this place, why no CCTV at the gate area to see intruders? They put electricity on the hole covers, but didn't simply put up a warning sign telling people not to remove the covers? These guys were some sort of miners? Don't they have a lot of explosives to blow up the whole cavern network and collapse it? And what are these things anyways? Ant people? And if they couldn't get out, what do they eat? While we're at it, what do these miners eat? I don't see them growing any vegetables or raising livestock. But perhaps most asinine is that the scientists knew there were something down there and after they climbed back up, they didn't bother to cover up the hole again and put the electricity back on? Even if they didn't, I mean it is pretty common sense to cover the hole and leave everything back to the way they found it.

The trailer wasn't bad but the movie sucked. If Will Patton wasn't in it I never would of watched it. All this movie consists of is people running around in the darkness. There was also no clear explanation on what the monsters were. And they never show you a clear shot of what they look like. All you get from whatever these creatures are is a bunch of annoying moaning & groaning. Movie was a waste of time. 4 stars.
