OK, I see only negative reviews here, won't go bashing them, everyone is entitled to his own opinion, therefore I am going to present you mine. So let's see why I enjoyed "Deep in the darkness".
Well for starters, it's a horror where bad decisions aren't taken at every step and boy did that feel good. Quite refreshing seeing people using their brain, trying to survive and not fell for the dumbest traps possible. Afterwards, the acting was good, believable. The creature concept I see is a hard pill to swallow for most, I for one think it is simple and easy to go with. I approve to it! You get to see a few deaths, a few fight scenes, some interesting facts about those creatures, and other variables making their way throughout the movie, making it more complex than your usual B horror. So all in all, in my books, this is a winner, as I enjoyed it, and stayed for the entire ride.
Now, as I am putting down this comment, the score is 3:1 for the negative reviews, therefore it will seem hard to take my word for it. But, if you are a horror junkie, if you approve to more underground productions, this one is smarter than most. It has more to offer, providing a good plot, execution and minutes well spent. Therefore, I recommend "Deep in the darkness" as I missed a woods/creature horror, done right.
