Fascinating ideas.

Can I just say, I think Iron Sky could be a massive hit- a fantastic idea; a real original twist.

I like the way that all the stories have been put together- that's great. As an opera, I am a little bit worried about how so many things can take place on stage in such a short time span (I might be wrong but I am assuming that this will be a stage performance). Does Jonathon need a (human) companion or to meet someone who he form a closer relationship with?
My biggest concern is number of specific references to elements on the internet. Someone like me who uses the internet all of the time can see the humour in this but someone like my wife who uses it fair amount won't have heard of half of the stuff you mention. It could end up being a bit of an 'in-joke'.
