I was discussing this with johnnyringo.
How about general grievous is like a HAL computer that controls the battle droids with its exceptional general leadings... So we can have less fancy action and return to old claustrophobic feeling.. No coughings no 4 sabers just some 80s cold english man voice to set some values about human and robot discussions. General HAL can be from the TPM under teh commands of trade federation until like brainiac from superman takes the lead for some reason.
We can have a machine vs man concept. Until Vader comes that he is the first that combines that 2 elements. Machine and man.
General HAL can create many plot twists and lead the jedi to wrong conclusions. Or at the end how can this happened? We are smarter than this(a computer) or maybe not.
