Great story but the finesse in the execution was a bit lacking. It's a great movie if I just go with the flow and don't think too much about realism. For example someone just telling absolutely personal life details when stuck in a house during the snow and telling everything just in the name of a game to people he hardly knows!! It's preaching in the end what many films have highlighted multiple times as social issues. And this preaching suddenly starts off abruptly leaving the main plot behind. Maybe could've been conceptualized and presented a bit differently.
