How did so many people rush to watch this Netflix offering when it was just a play on the already trash talked M. Night Shyamalan offering The Happening? That's not to say this movie is bad, it's just that we've seen this before, only this time we aren't even given a ridiculous reason as to why it was all happening (no pun intended). There were so many missed opportunities here not least that this could have easily been better delivered as a tv series rather than a movie, which in turn could have delivered those all important answers to the burning questions this film left us with. I so wish they had switched the sister roles around and had Sarah Paulson play lead instead of the almost forgotten Bullock. I guess the worst offense here is the lack of reveal of the 'monsters', moving leaves and formless black smoke does not make anyone tense watching. It didn't even need to be a full reveal straight away, glimpses, reflected moments in the eyes something to provide some sort of pay off. Coming in at a not so healthy second for worst offender was the saccharin ending but I guess Sandra had to have her happy, cheesy string ending. I had this rated at a 7 but realized after typing all this the movie hits a decidedly average 5 !!
