When their conversion to goodness is discovered by Lucifer, a young devil and his converted, ‘goody two shoes’ family flee Hell for the suburban life of Canberra where the boy finds that being a horned, red-skinned devil and ‘fitting in’ to Earthly life is not as easy as he thought.

Thanks Tony. Yes, you're right but I was thinking of The Munsters and The Beverly Hillbillies, though with a refugee twist (the three series mentioned are just fish-out-of-water comedies, ie with no social undertones attached to them).

Some great feedback above.

I think your last draft is pretty good. In fact, it could almost be pitched as a series, just IMO... a modern day riff on the Adams Family/ Munsters ;)

Best of luck.

For purposes of structuring the concept a vague notion of a known theological paradigm can work. However for pitching all elements of a logline need to be immediately clear for most readers with out a need to look at "...two differing themes from two well known theologians?".
