You guys are defining friend way different than I would. Han and Chewie are friends. Luke and Han are friends. Lando and Han are friends. R2 and 3PO are friends. Watching their characters interact, you can tell that they enjoy each other's company. They laugh at each other's jokes, they help each other out, they worry about each other, and they SMILE at each other. When have we seen Obi-Wan and Anakin smile at one another? Has Obi-Wan ever said anything to Anakin other than telling him to act more like a Jedi, to remember his training? Has Anakin ever done anything but whine to Obi-Wan? And wasn't the only reason Anakin went to save Obi-Wan because Padme wanted to? If Obi-Wan had said in ANH, "He was like a son to me," I'd buy Anakin's line, "He's like a father to me." But Obi-Wan said friends, and friendship and father-son relationships are two entirely different things. The climactic Obi-Wan-Anakin fight isn't going to be a dramatic and hesitant brawl between two best friends, it's going to be student versus teacher, and the latter is a much more boring event than the former. Epsiode I should have been a buddy pic, like Lethal Weapon or Bad Boys.
