Took my DD to see this on Saturday and was a bit 
at some of the language considering it is a PG. Words such as bullshit and holy shit feature and at one point the angelic daughter utters the line "everyone calls you a dick but I don't think you are". This prompted the girl sitting next to me to ask "mummy, what's a dick?"
Apart from that, the movie was a lovely tale of a family coming to terms with bereavement and taking on a new adventure, make sure you take some tissues.
Both children give great performances and I always love to watch Matt Damon although here he is a little chunkier than in his Bourne days. Still has that wonderful voice though.
