I'm going to make negative IMDB comments for a short film and thus make one person involved with the film mad.
What are your motivations for doing something like that?
The director of the movie has been really mean to me since we broke up.
Even if you're only stating the facts there's no reason to upset people. Don't do it if it will make someone mad.
How else could I punish the director for dumping me? It's just not right to not punish him after he dumped me.
I know that you are upset with your bf for ending things, but criticizing their work on a movie has nothing to do with your relationship and using this tactic to upset them is not correct. Move on and find someone better for you that loves you and cares about you.
