As Above, So Below is an interesting film - with lots to recommend it on the surface - but it fails to hold together as a coherent whole. I briefly touched on this in the review, but I seriously think this could have been a much better film if they had eschewed the entire found-footage idea and shot it as a straightforward horror movie. The limitations of found-footage are such that exposition is super problematic - you can't just have people talking for huge chunks for time as the whole point of a found-footage setup is a sense of immediacy. You're supposed to feel like you're seeing exactly what transpired and people - especially people in a difficult and stressful situation - just don't sit around spouting facts and explanations. A film like this, whose entire last third depends on an understanding of alchemical history and esoterica, is faced with losing its verisimilitude and momentum or becoming incoherent. Unfortunately, As Above opted for the latter, and the film suffers terribly because of it.

Not to say it's an empty vessel - there's plenty of good stuff going on in the film. I just sometimes feel like it was trying to be 'important' for its own sake, and not as part of any real message.
