i know this movie will have it hater and they will have some credible reason . i have never hear of it but it one that i stumble upon today on tv and can not get it out of my mind now almost 12 hour later . the closing music by tangerine dream if it all over be both hauntingly beautiful and emotionally sad . the question throughout the story be be the attack real and or a prank and or a dream . i would not present any spoiler but i have to admit i wasn not prepare for the end . i be very surprised and maybe shouldn not have be . if you ever get the chance to see it do so . a i say and there be fault with the movie but overall it a thought provoke movie and on it own term terrify . what would you do if you believe the end of the world be come in less than one and a half hour . perhaps part of my liking of this movie on a subconscious level be my own brush with death a few week ago in a potential drowning incident and have 60 second to helplessly struggle for survival and really believe i might not survive and may really have meet my end . for the first and only time in my life i experience the true panic and fear of the end . fortunatly there be an emt and firefighter on a boat that pull me while helpless to safety .
