Most everyone hates Jar Jar. Thatís a sad, but true fact. Your ideas about him may change after you read this.
Without Jar Jar the Star Wars Universe would not be the same. There would be no Luke and Leia. There would be Darth Vader. If you watch TPM when R2 makes his debut you see him bump into Jar Jar right before he goes up the elevator to fix the Queens ship. He runs right into Jar Jar, which in turn delays R2 ability to get to the elevator. If R2 would not have bumped into Jar Jar he would have been blasted by a laser bolt that flies right past his head when he reaches the top of the ship. So, Jar Jar saved R2 life, who in turn save the lives of everyone aboard the Queens ship. Not to mention all the import stuff that R2 may do in episode 2 and 3, plus we know how important he was to Luke and Leia and Han.
So as you know see, the universe would be different without Jar Jar. So we should all thank our lucky star for him. Even if he is a bumbling idiot.
