I'm a TOTAL whimp tbh... it would be easier to list the movies which DONT make me cry.
But to list a few of the worst offenders -
Grave of the Fireflies: If this movie doesn't make you cry, you have no soul.
Where the Wild things are: A truly beautiful film, I was worried when they said they were turning one of my favourite childrens books of all time into a movie, then I saw the movie.... 5 times.... the first day.
Mary and Max: a very wierd claymation film, about a young aussi girl who becomes pen friends with a newyork shut in.
Saving Private Ryan: That salute :'( right in the feels every time.
There are more, but I'll leave you with just those.
