^Apologies, I misread your reply.
Personally I think the midichlorians just aren't a terribly good way of accounting for how force users...urrr...use the force. Bit of an odd example, but it reminds me of people who claim that the "aliens seeded life on Earth" theory is a valid way to account for the origins of life. It doesn't, it just passes the proverbial buck.
"How do Jedi and Sith access the force?"
"...OK, so how do midiclorians access the force?"
"...umm....hey look! A rabbit frog is doing slap stick!"
