Way over most people's heads...
It's fine if you don't enjoy found footage movies anymore, I actually think this would have been much better if it weren't.
What is lacking though is people understanding the background of historic alchemy and literature in this film though. And not pop literature, but something most educated people have been, or should be, exposed to. That is Dante's Divine Comedy and his journey through hell and purgatory. It's pretty obvious that was what the movie was going for. It's sad to see most people didn't get it. WAY too many people taking the movie literally, and then wondering what happens with them at the end. It was obvious to me what was going on well before they entered the catacombs. I suggest many of you take a look into Dante's work. You'll see a lot of influence here.
