I wasn't particularly thrilled with the addition of Midichlorians either, but I think too many fans (or former fans) have focused on them far too much in the last 5 years. I mean, think about it; their impact on the overall story has been pretty negligible. And remember, the OT had deeper roots than just "Space Opera," however you want to define that. The old Flash Gordon serials had lots of psudo-science gobbledegook, just like the many pulp Sci Fi stories published since the 30's.
They were mentioned in 3 lines of dialog, people. Time to get over it and move on.
