And I'd even take making the Jedi dogmatic, baby-snatching cultists if that had actually been on purpose. If they were portrayed as decadent hypocrites who had been suckling on the Senate's teat for centuries, growing fat and indolent and becoming completely impotent, while simultaneously having all of their transgressions sanctioned by the Senate because having the Jedi in their pocket was convenient, then it would have introduced some much-needed moral conflict, and might explain why the Dark Side is tempting ('We're honest about being evil, at least').

But Lucas has a very poor idea of what makes for interesting drama, so we have Jedi who are extremely morally questionable on accident, with a PT full of Broken and Lost Aesops being written by a guy who is a terrible writer.
