Three months have passed, so it's time for another issue of the Curious British Telly fanzine. And, as per before, you're guaranteed to find a curious selection of essays, reviews, meanderings and quizzes within its 40 pages. The Curious British Telly Act of 2012 demands, of course, that this content should be both a head turner and a head scratcher; issue four doesn't disappoint on either count.
