Ok, I caught the re-airing today, 11-12 Thursday.
I). They introduced the topic.
II). They concentrated on Jenkin's enlightenment and disaster scenarios. (For those of you who do not follow, Jenkin's belief of 2012 is generalized to encompass nothing taking place).
III). They allowed both to search for what they believed to be evidence.
IV). They also talked about myths that may be indicators of past disasters. (Mythology is an interest of mine. Mythology is the study of ancient stories, and according to mythology the stories are aimed to: A Explain unexplainable events often as the wrath of God, B grow as a person C to prepare you for the after life)
V). They talked about three extreme theories (or truly opinions) of global cataclysm (opinion since there's no concrete evidence)
VI). The show concluded saying roughly that what will happen on 2012 is speculation.
In my opinion, I thought that the showing was objective in its approach. They did talk about some kind of structure in Egypt that caught my attention, but water distorted the picture from basically sonar (at least I thought that was interesting).
