well, I can see your point, but I think it does well not to dumb down the force as much as many people didn't like when Qui-Gon explained medichloriance (which is funny because it had to be explained).

It doesn't explain it at all, just that there is more to know. The conversation I'm adding doesn't explain that much... it simply hints to the reality that Qui-Gon is back and there is more to know... and you're right that it does seem to slow down the action of the film, but In a way it feels kinda nice to have a little exposition and be able to place Qui-Gon in the film.
