Cosmos - ;_;
Why does this show make me emotional? It makes me so hopeful of the future, that I almost want to get off my bed/couch and participate it making it happen (except it's usually after 9pm when I watch, and wouldn't know where to start or possess the correct degrees to participate in the creation of the future as I imagine it at this moment.... I know, excuses, excuses.).
This show just seamlessly blends History and Astrology with Geology, Science and Technology that you end up learning so much in topics you previously couldn't have cared less about... it actually makes you care and become aware and hopeful. It presents ideas followed up with facts/data/examples/graphics/charts or whatever is needed to illustrate the point, and explain it in a way that just makes sense to the average viewer w/o ever talking down or attempting to push the point above your head or shoe it down your throat.
If you haven't been checking this show out this season, I highly recommend it. There is one episode left for season 1 which airs this upcoming Sun or Mon on Fox.
edit: This is the type of show that I could see being shown to the Science/astrology class in a middle/highschool or something. Show the video, have a discussion, do some experiments based on what was discussed and then move on to some related stuff until you do the next episode.
