The story is incredible. For a filmmaker who wants to create a science fiction movie, this story is like a goldmine. The locations chosen for the film are also very successful. The eerie, unsettling nature of the environment effectively amplifies the fear born out of helplessness. I genuinely wanted to give this film a high rating, but there are several flaws in it. Here's why:
The balance between the horror elements is not well-established. At times, scenes are overly frightening, while at other times, there's an odd calmness.
There are issues with the acting as well, though it's not due to the performances of the actors. The problem lies in the transitions and connections between the characters. There is almost no dialogue between the family portrayed in the movie and the other characters, which weakens the sense of realism.
A better storytelling approach could have been achieved, but many opportunities were missed. I don't think the problem is the budget, either. In its current form, the film has the potential to evoke the kind of fear that big-budget American sci-fi films can create. The issue isn't with the visual effects; it's with the screenplay. The flow of horror elements and the inadequacy of the dialogue's narrative seriously impact the film's success.
The audience feels scared, but they cannot fully connect with the film. However, I'm sure it won't take long before Americans buy the screening rights and create their own version. With a massive budget, they'll probably remake this film and won't even mention its name. I only wish this film had been executed better.
