Frontline's "Journey to the Occupied Lands" is definitely biased, but unlike some other similarly biased documentaries, the filmmaker Michael Ambrosino does allow Israeli settlers to speak for themselves, though he does not necessarily allow them their best arguments.
I was unimpressed that he spent a great deal of time on the case Sabri Sharib, a Palestinian who claimed ownership of a large tract of land as a farm which was subsequently turned into a settlement. As it turns out, he was proved to be making it up...by Jordanian land records that showed that it had been owned by a Pre-state Jewish company and was being held in trust by the "Jordanian custodian for enemy property," no less. This had been resolved in 1986 and Ambrosino could have found it out with a few minutes of research. Also, he makes serious errors in his treatment of the six-day war claiming that "technically Israel was the Aggressor" when it is well know that Nasser's blockade of the straight of Tiran was technically the first act of war in the conflict.
Still, I use this video in my Middle Eastern Studies class to capture the flavor of the time period and Western pro-Palestinian sympathizers. Also, I have the students use it as evidence in a debate, partly because I show it after several pro-Israel documentaries and because the Israeli side of the debate and easily find it deficiencies if the want to.
