Both Frank and Debra (as well as Patricia Heaton's new character) are ISTJ's. They're just like my parents. He's not an E (pretty much wants to be left alone watching TV), and he's not a P either (seems to like familiar order). His crankiness is reactive, not expressive.
She may seem like an F, because ISTJ women generally retain the "traditional roles of women" they were taught with their dominant Si, and we associate femininity, emotion, and a focus on what's "appropriate" with Fe. Her reactiveness is also not E, but just a younger, more female version of his melancholic crankiness. They're both clearly Chart the Course, and Guardian.
I think Marie is probably the ESTJ. Again, traditional female role appearing Fe-like, and also, people thinking any overbearing personality like that is ESFJ. Clearly an In Charge (not Get Things Going), and also seems to be Guardian.
