OK, OK, don't kill me! This is something that I've noticed about Star Wars that is very annoying to me. The annoying thing is this: it's inconsistent. I mean, think about it; things that happen in the prequels aren't always consistent with things that are said or happen in the OT. Part of the problem is the fact that the prequels were made long after the OT was. For example, in ANH, Obi Wan dies, and his body vanishes. In ROTJ, Yoda dies and his body vanishes. But, again in ROTJ, Anakin/Vader dies and it doesn't appear that his body vanishes, and in TPM, Qui Gon dies, and his body doesn't vanish. So, do all jedi vanish when they die, or do only some of them vanish? You can't tell from the movies.
In, ROTJ, Obi Wan tells Luke,"When I first met your father... I was surprised how strongly the Force was with him." In TPH, didn't Qui Gon find Anakin and realize all that stuff? He also says," I thought I could train him as well as Yoda." Was Anakin ever supposed to be trained by Yoda? Obi Wan also makes it sound like he was trained by Yoda, which we know isn't true since he was trained by Qui Gon.
