While I don't want bad reviews, it was interesting. It boiled down to "He tried a new thing which didn't work" - The Imposters is something of an experiment and one of the questions was whether it worked at all (I think it does, funnily enough!).
It is a super cover. I am in now way responsible for this: I suspect that I was exactly the sort of person you don't want involved. My input boils down to "Like this, except not, bearing in mind that I have the power of veto here".
