Basically that. I really don't care for films based upon the conceit of vlogs or online influencers and all the 'hip' comments and likes, etc. Just not my thing. BUT... once you get past all that, and I can see how it was somewhat integral to the story, the way the plot proceeds is actually done quite well.
The acting is excellent and the writing I feel was sharp. The reactions of the people helping here I thought were quite genuine. Usually in a film like this it is the poor acting that really kills it, but not in this case. At the beginning I admit I was FF it through all the YouTuber stuff, but when I got a ways into the story I slowed down and as I watched I did get more and more drawn into a rather strong Mystery of what the hell was happening.
It actually turned out to be a very good Psychological Thriller with good Horror elements. Like I say, MOST times with movies that try to do something like this, usually the acting/writing just isn't that good. But, in this case as the mystery drew you in deeper and deeper, I really found it quite gripping and very much intrigued to know what was going on.
So yeah, if you are like me and all the 'Hipster' online stuff makes your eyes roll back to the back of your head, stay with the story and you'll find that the original online conceit fades a bit more into the background as the actual story of what is truly happening becomes more apparent.
I'm glad I stayed with it, even after rolling my eyes and FF the movie a few times at the beginning, because at the end I felt it was actually a very clever idea and that the filmmakers did a very good job in putting it together, along with quality acting throughout. If you like a good mystery and if you can get through the first 15-20 minutes or so, once the 'accident' happens, from that point on I think you may very well find this quite an engaging and mysterious Thriller.
