The Impossible

Last night my friend and I went to see The Impossible, a film based on a real life families survival of the 2004 tsunami in Thailand and oh my was it traumatic!
I am not one for crying in films but I think tears flowed from beginning to end - my friend said she cried all the way home too.
Whilst I thoroughly enjoyed (which seems the wrong word!) it I'm not sure I could put myself through watching it again - not without thoroughly preparing myself first
