Did you find Cammi disgusting?
I read an online review which summarises Cammi perfectly:
"Cammi isn’t a victim but is in some ways the most servile server, a cog in the system, a fat person who watches a lot of TV, the ugliest American, an ignoble and ignorable woman who doesn’t fit the pretty archetype or the picturesque wine country scenery. She’s the person who is almost always left out of conventional cinema, an Other whose highest aspiration is to sleep with a minor former celebrity from One Life to Live (and what a fitting title), referring to Jack only by his character’s name, Derek. Cammi reflects an instantly recognizable underclass in America, that most slovenly of poorly educated Hollywood bus tourists hanging out the windows and ogling stars’ homes, howling 'Hey, look, George Costanza!' at Jason Alexander."
