I don't think that this is a massively bad film, I'm sure it was groundbreaking to some people when it first came out ten years ago, but now with all of the cheaply made and dreadful bad "found-footage" movie copies that came soon after, it's probably lost some of it's impact when viewing it nowadays.

The things I like about this movie are the well-designed set pieces that we sadly don't get to see enough off, due to the "found-footage" format that is present throughout the film. Another thing I liked about this movie is how they decide to go with the "Jaws" approach, not showing much of the monster early in the film, to the point where we can see the creature staring directly at us through the camera lens in a later scene.

I thought the acting in the film wasn't great, as in Oscar-worthy material, but I think that it's not too bad to drag me out of the story either. All actors did a good and satisfactory job at portraying their characters. However, If I have to be nit-picky, I think that T.J. Miller is possibly the worst actor in the film, but we don't get to see him a lot in the film as he's the one documenting the action a lot of the time.

A few things I like to bring up, I have to give this movie credit for not "cutting-away" from intense moments after they happen or when they feel like they may be too much, so that there are very little moments of relief from the tension as soon as the first explosion is heard and all the lights go down. And lastly, the CGI in the film does look unrealistic at times, but I think it's acceptable considering the age of the film.
