First the bad news: Particles of Truth is a real mope fest of self-pitying characters, each trying to out- dysfunction the other.
The main character, Lily (writer, producer, director & star Jennifer Elster) is an emotional mess because she was the product of a screwed up family (surprise!). She is an unappealing and unsympathetic character and that is the crux of the problem with the film.
Another problem is that none of this suffering is, in any way, new or interesting. We've seen all these gritty, pathetic people before. To make matters worse, some of the dialogue is cringingly pretentious.
Now the good news: Queer as Folk's Gale Harold is great as Morrison, a reclusive germ-fearing writer. He is the strongest, most likable and most realistic character in the bunch. He and Lily develop a tenuous relationship that scares her to the point of puking in his antiseptic bathroom. Despite Morrison's fears, he admits to Lily that he cares about her and proves it by venturing into the subway to find her (a germophobe's nightmare). He also manages to pull himself together to attend her art show.
There is real chemistry between Lily and Morrison and there is something endearing about watching these two people, who find it so hard to function in the world, manage to come together.
The soundtrack is great too.
Oh, and Gale Harold looks better in a shower cap than any man has a right to.
