With all of my films if I get one bad review and a bunch of good reviews the bad one is the only one that will stay with me, which really sucks!
And, if I were so low that I accounted myself the worst of all, yet some would account themselves in worse case.
I always start with characters rather than with a plot, which many critics would say is very obvious from the lack of plot in my films - although I think they do have plots - but the plot is not of primary importance to me, the characters are.
