As with much academia- you can take it or leave it, as it is just written to fill a niche. This would be a fairly good book to consult if writing on Science-Fiction film- though it is far from definitive. The "Phantom Menace"-piece at the end is almost as bad as the film itself; that is the problem with film academia: the subject can be turgid, but lots of critical readings can be made. It is hard to see the point, other than defending the increasingly tedious realm of the £££$$$world of academic research...The essays are all of an acceptable quality- though discussion of the drivel that is 'Tank Girl' outside of its comic-book roots is rather misguided. That film was excerable & is not fit to be referred to- other than the bastardization of concepts by Hollywood to make a quick buck. I think books like 'Screening Space' & 'Terminal Identity' are much better than this book. We get a few SF key terms- but nothing on the level of 'The Encyclopedia of Science Fiction'. The filmography in the back is a good representation of Sf- but does miss films like 'Last Year at Marienbad', 'Crash', 'Eraserhead','Seconds' & 'Until the End of the World'- which I feel all qualify as SF. I believe JG Ballard's section on SF in 'A User's Guide to the Millennium' is much,much better; ditto Susan Faludi on 'The Incredible Shrinking Man' in 'Stiffed'. This book is fine for undergraduate uses, but only a mild source of interest for the postgraduate. The best book on cyberspace is 'Escape Velocity'. Though I think this book merely confirms a lot of recent SF-cinema criticism- as seen in 'The Cinema Book'& doesn't really tell me anything much I didn't already know. Perhaps this would have been more interesting if it overlapped with other mediums, the futurist notions of recent pop culture: electroclash-Alan Moore-digitalcamera use-arhitechtural design-the banality of the millennium etc etc- which SF in a multitude of forms deals with best. To restrict the scope to cinema, with the odd reference to 'Buffy', is not enough. 21st Century perceptions for the 21st Century are what we need...
