I enjoy the opportunity to use swear symbols. The reader reads into them something worse than what you normally would have. They work as this outburst of incoherent anger. I've found ways to write around swearing that are much more effective, rather than going for what someone really would say.
Certainly my films are cinematically unusual, and quite contemplative in their pacing compared to conventional films, but I think overall they are quite engaging, accessible, and even funny.
