Will the movie lose some of it's appeal if viewed on a regular TV?
Yes.
But that's the same with practically any movie, really.
And as for the redheaded cultist sounding insane, I don't think so. She came across as trying to sound crazy/brainwashed. If that is the case (which it obviously was), then she did a fine job of it.
