I liked this. Atwood's style is easy to read, often shot through with wry humour. Some of the non-fiction about SF I've come across can be so very turgid, so it was nice to have something readable.

It's a collection of pieces rather than a sustained argument. Doesn't make it any better or worse than a more cohesive text, just different. If there's an overarching theme, it's on Atwood's own personal relationship with SF. I found the chapter on Orwell particularly interesting - partly because it's one of my favourite books, and partly because of the personal connections Atwood drew with her own novel "The Handmaid's Tale".
