From the Dark was a pretty good little thrill-ride, even if it's not the most flawless or intelligent film.
Basic plot: After their car gets stuck in the mud, a traveling couple have a run in with a creature that cannot be in a source of light. As the creature slowly diminishes their sources of light, they fight to stay alive and evade it.
Without spoiling too much, I will say that this film is basic survival horror without much story to bog it down as anything other than a simple little horror flick for mindless entertainment. The atmosphere is bold and the direction can be pretty creepy, even if the bold and interesting camera work can sometimes make it feel like too much. Still, major props for building a movie where you spend so much time paying attention to the background for the thrill of seeing something that isn't obviously there.
I do see many complaints from other viewers about the fact that there were a handful of light sources that were overlooked by the main character, but I must say, when thrown into every situation, do you often notice every detail or think clear enough to make the best moves possible? Apparently if characters in horror films aren't the brightest and sometimes make poor decisions, then it is unbelievable and a bad film. Heaven forbid anyone is flawed, ya know?
As far as finding light sources and just staying in them til sunlight, I do believe those people weren't paying attention. The creature was not entirely stupid or slow. Trying to remain in a light source without moving only led it to find ways around it and cut off the light. Even setting an entire house on fire wouldn't have been the safest mood: fires get out of control and I'm sure no one wants to burn to death.
Those things aside, horror films like this are pretty much built around the trope of wanting you to scream "NO! NO! DON'T DO THAT! DON'T GO IN THERE! IT'S RIGHT BEHIND YOU, STUPID!" which I think adds to the thrill.
So all in all, no, the movie isn't genius and it's definitely not a 10. But for what it is, it's a successful little thriller chiller., sure to appease people looking for something simple and creepy. Fairly solid, but not groundbreaking.
