Chronologically its completely and utterly pointless, for some reason it shows that suppose to be only 4 tapes plus some surveillance footage, however they actually show a tape 5 and a tape 6, and then when they show that its 2:42am you can see that its light outside, and I mean Broad daylight, like 1pm type lighting.
Now what I think happened here is that they had a different movie in mind but couldn't finish out their original idea for one reason or another, then because they had so much footage shot, they decided to bank a found footage horror type movie, which you can not do unless you actually are doing that, so because of that most of it doesn't make any sense, very little happens and the ending is the worst possible ending for this type of movie.
All I can say is that if the director and the writers ever should read this post, please watch Area 51, Flight 407, troll hunter and then go back and look at your movie, and then RETIRE please.
