I don't understand people complaining about a inconclusive ending!!..are they dumb?..it's clear that theres gona be a sequel and it's gonna take off from where it ended in this instalment.And this one was quite good.I mean it was natural and fresh.You don't need to show buildings falling,planes crashing or zombies or other such things to portray apocalypse..this movie is more of a journey by a father and a husband in search of their daughter and wife respectively.And it's well directed.And it does end abruptly but because it ends midway.And the rest is about to follow in the next movie.If this movie was released as a 4 episode series,people would have gone ga ga over it.And its a movie clearly on geolgical apocalypse.
Sad that people didn't realise this.
