Who's telling the truth?

Zeitgeist provided an exciting start to the Symposium, albeit with technological glitches. There wasn't too much controversy over the film when it came to a discussion, with many people arguing that we shouldn't believe all the hype. Is that educated students speaking though? Would the opinion be different in the high street?

In contrast to the style of Zeitgeist, the screening of Errol Morris's Thin Blue Line surprised a few students. Should we the audience be presented with a truth (like Zeitgeist) and decide for ourselves over its validity? Or should we be presented with various truths and decide our own (like The Thin Blue Line)?
