Have any of you seen the psychological thriller/horror film Pontypool? It is set in rural Ontario. The three main characters are very interesting and very complex psychologically. They work at a local radio station. Grant Mazzy (morning man) is a shock-jock, the producer is a control-freak and the techinical assistant is a nice and witty introverted young girl just back from a tour of duty in Afghanistan.

I can't figure them out, I'd like to have your help on it if you've seen it.

Here's my take:

Grant Mazzy (morning man): ESTP
Sydney Briar (producer): ESFJ
Laurel-Ann Drummond (technical cowgirl):INF INT ISFJ? ()
