Query: gripping and genuinely unbiased British documentary

This is one of the most gripping documentaries I've ever seen. The more nobel aspects, and the less morally sound aspects of both sides are covered in detail. Excellent work created by 1 Palestinian and 1 Israeli for the BBC (even though the blurb above calls it a PBS show, and indeed so does the generic intro on the DVD - it was actually made by the BBC, not an American company, just thought I'd clear that up)
