I suppose comparisons between this episode (and its follow up, Forest of the Dead - it's hard to review them separately, so most of my comments here apply to the two as a combined story) and Blink are inevitable given that they're both written by Steven Moffatt, both excellent, and both scary as hell. Even the beginning fragmentary warning "If you want to live, count the shadows" is a bit reminiscent of Blink's "Don't blink, or you're dead".
However, given that Blink tends to be pretty widely regarded as the best Doctor Who episode ever, there are far less promising ways to start a new one than evoking it. And overall, Silence/Forest doesn't come across as derivative at all. Both of them are very fast-paced and alternately terrifying, tragic, touching and funny, but beyond that the themes are very different. This story is a lot more complex and thought-provoking, packing in enough really interesting ideas and twists that even spread across two episodes, it keeps you constantly on the edge of your seat and never drags at all. It also includes some really top-notch performances from some of the cast, particularly in Forest of the Dead.
All in all, one of the best episodes (or pairs thereof) yet, and good reason to look forward to Moffatt taking over the series in 2010.
