Jar Jar's an abomination. If the Galactic Empire ended up killing him then the fall of the Republic was a price worth paying
I've not seen the last prequel film yet, but the first two did not measure up to the original series. Qui-Gon's special skill seems to be being rubbish, and Obi-wan Kenobi has all the charisma of a plank of wood. Anakin shifts from being an annoying twerp in episode 1 to a tedious, stroppy twerp in episode 2.
Still, I did like Mace Windu, the Emperor and Yoda.
