This movie is one time watch only, and not a movie if you want a great evening or day, I seriously watch this on recommendations from my friends but it was total waste. I could've done so many other things if I didnt wasted 2 hrs on this, trust me you also don't need to. The first half is fine apocalypse happens so ppl dies and it's survival of fittest, alright. but there are so mNy freaking things that's been unexplained like how come those lunatics aren't killing themselves and finds those mysterious entity beautiful. But kudos to Sandra Bullock, she nails the character and is badass , plot is somewhat guessable , at least mine come true . Direction is lame and plain it's nothing new. But your time is yours decide what to do with it.
