My dream prequel would have been called Star Wars Kids: The young Han, Luke and Leia chronicles, and would have had our 3 heroes (plus the occassional appearence of little chewie) as 8 year olds getting mixed up in all kinds of wacky adventures. Of course, in the last episode they all get their memories wiped in time for a new hope.

Any adventure suggestions anyone?

Seriously though, I imagined the prequels to be of a more similar tone and style to the OT, probably because it would have been made in the 80s or early 90s, and would have featured a young Obi Wan and Anakin as principle characters, like the actual prequels. The kickass lightsaber fights were there too, but nothing else. I don't give a crap about Boba Fett, never did, and any mysterious coolness he once had is lost forever now anyway.
