It was an incredible movie. It was so intense and emotional. I had really huge doubt since it seemed too cliche also the fact that it was filmed like Cloverfield (which would’ve been great, except the filming was extremely HORRID). Except the camera filming problems were overcome easily. [spoiler] They were able to float the camera using their telekinesis and thus able to achieve better viewable camera angles in the air and it can be easily explained by the plot.
