I stopped rooting for them when...
it was revealed Ewan McGregor and the kids survived. After that I stopped caring what happened.
Obviously it's an incredible story that all five of them made it out of there (it's not called The Impossible for nothing) but I couldn't stop thinking about everyone else who had lost so much more than a family on holiday. I know one of the biggest gripes about this movie is the "racist!" argument, but what irks me even more is the decision to focus on a family who made it out of there with all five people intact and only one critically injured... who was flown out days after the disaster on an expensive private jet.
