I just got round to hearing this on the podcast, and not having got the show over here yet, I have to say...
I kinda like the sound of it. Rather than being put off by the 'God left' intro, I'm intrigued by it; I think it's an interesting premise to explore, from a Christian perspective or otherwise.
I appreciate that the concept isn't scriptural, but I don't think that matters - it's just a story after all, and unless the storyteller has specifically stated they want the story to be taken as 'Biblical' in any sense other than having the angel Gabriel in it... well, that's where suspension of disbelief comes in.
I can't offer much of a counter argument to convince you to watch it, because for all I know you may be right and it may suck on every other level; but you might have been a tiny bit harsh to write it off in the first few seconds.
That's what I think anyway.
