As with the first two episode guides, I've been reading this at the same time as watching the re-runs. It's been good, enjoying the episode and then reading about the background - either from the writer, director or actors point of view. The introduction about the special effects, was a bit on the boring side - I guess that since this has been written, FX's are more common and are more widely known about - so I have to admit I only briefly skimmed this. However, the rest of the book was well written and enjoyable.
