Not really getting the 1 or 10 reviews.

If one ignores those you will find a perfectly adequate film. It fits better into the category of psychological thriller(with limited thrills) than horror or scifi.

On to the review:

Acting was decently done considering the fairly weak script.

Lovecraftian storyline(just seeing the creature makes you go mad) has never really translated well to film and this is no exception. Some mildly creepy moments.

Pace was okay, but honestly they could have shaved 20-30 min without a problem. Director seemed to be aiming for a slow burn rising to an explosive end, however in this case it just fizzled.

CGI and special effects were non-existent. Wouldn't have been a problem had the premise or dialogue been better.

Overall, don't regret seeing it, but there is not a lot here to recommend.
