I agree with most of the comments I read, in that this film is definitely worth watching, BUT thought I'd mention a few things that others didn't.

The lack of a steady camera shot, even though it fits well with the plot, began to wear on me. I found myself relieved whenever the camera fell to the ground and gave the same view for a few seconds. It felt like I had on the wrong glasses - I was constantly trying to bring the scenes into focus and the continual motion, coupled with the random focus and quick glimpses of things I wanted to see clearly, made me feel stressed, strained and then annoyed.

Add to that the ending, which leaves so many issues dangling, and, overall, I found it very unsatisfactory.

Despite that I still gave it a 6. If you can handle triple rides on a roller-coaster then you'll probably really enjoy this film. If you get motion sickness easily then you may want to pause it every 10 minutes and focus on the wall!

I genuinely enjoyed this movie and found its concept to be interesting. However, I do know some other people who have not enjoyed the shaky camera style.

They needed Godzilla to fight that thing, not tanks or missiles!

Jokes apart, it's a well-acted and well-made found footage feature, no doubt whatsoever. However, I remember liking the movie much more when I first saw it in my teenage years. I vividly recall caring for the whole ensemble and the devastating tragedy that struck them out of nowhere.

More than a decade later, I cannot state the same, though. Perhaps it's the overexposure of the found footage genre in general or the fact I've now gotten habituated to such filmmaking and have seen much better works in the process. Whatever the reason, it did not resonate with me on the same level this time; I wish it did.
