I can't help but constantly think of Unfriended when I see this. I know the concepts are pretty different, but the names are way too similar. Anyways it does have a fairly decent cast. I've never heard of the director or the writers though. It's not received very well, but I'm going to give it a shot because I'm curious.
Wow this is extremely similar to that of Unfriended with the whole concept! The only difference is that this deals with Facebook and it's not found footage. It reminds me of Cyberbully and The Den as well. I think cyber horror is an interesting sub-genre, but I wish they would branch out with it. Most of their stories are way too alike. On a side note Black Mirror had a really well done story about it called "Shut Up and Dance". I thought the usage of the interruption noise that happens with audio was an interesting idea. Despite it not being all that original I actually got a kick out of it. They really got in depth with details about Facebook which was cool. I'm not going to lie I did actually jump a few times. The story as a whole was pretty interesting. Some of the deaths were pretty intense. There were some good twists and turns. It got much better as it moved along. The ending was particularly good.
I thought the acting was quite good. At least three of them were in TV shows I watch where I liked their characters. I'm glad William Moseley still acts here and there after The Lion, The Witch, and The Wardrobe. Sean Marquette looks a lot like his brother and I'm not used to seeing him not doing voice overs. I thought he was pretty good though. I really liked the characters and how they were developed over the course of the story.
It's not too original given that this is a small sub-genre to work with, but I actually liked it quite a bit. The kills were crazy. The scares were good. There were some pretty good twists and turns. The characters were interesting and developed well unlike most of the movies you see like this. I think the ending really makes it more enjoyable too. I'd say give it a shot. It might be a hit or miss kind of movie, but for me it was a hit.
