Whinge, moan, whinge, moan... Let's face it, whatever George had called this film there would have been griping from some quarters.
And as for some of the alternative titles suggested by self-proclaimed SW 'experts' - 'Fall Of The Republic' - careful on the step there, Republic, it's wet... 'Birth Of The Empire' - keep pushin' Palpatine, we can see the head... 'The Creeping Fear' - Look, Darth's on tippy-toes!... 'Mask Of Evil' - jeez, no comment!!!!
Revenge Of The Sith works for me, and more importantly it works for a mass-market audience - the very word 'Revenge' alone conjures up thoughts of bitterness and evil, plus in its construction the title has a pleasing symmetry with ROTJ.
Even if you really, really, *really* hate the title (and god knows why you should, but anyway...), remember: it's only a name - it's really not worth getting that worked up about.
The Hutt out.
