I hate how people are criticizing this movie because of them I held myself back from watching it and now I have watched it I hate myself for not watching it earlier. This movie was great and had a realistic way of survival, I mean sure I wondered why the creatures can't enter homes/closed environments but that's the only problem. The movie was tear jerking, suspenseful, a bit scary and definitely not a waste of my time. I wish people will give the movie a chance even with all the negativity going around and decide for yourself whether it was worth it or not.
