Even so, I'm with Bossk on this one. It's not a terrible explanation; in fact, it's a really good explanation. But the mystery of it was all part of the fun. Though, maybe it's good to point out that in TPM, the Jedi Council doesn't use Anakin's midichlorian count to sway their decision to train Anakin or not. As long as we didn't have to hear Yoda say, 'Train him we shall. Many midichlorians has he. Trained he must be.' I have no problem with it.
