Tibbs: "Ugh...the whole thing with Yoda being pals with Chewbacca...ugh. The ridiculous amount of coincidences of people knowing one another in the trilogy is terrible. I mean, why couldn't Yoda just know some random wookie...heck, it would give you an excuse for another action figure. Just fucking stupid."
Lucas put Chewbacca in this movie for one reason: he hasn't created a single character in these Prequels that the general public likes. So, in that case, lets make a Wookie's life span 200 years & put Chewie in there, so we can put him on cereal boxes, toys, & Pepsi cans.
You're 100% right that the Kashykk scene could've held water without Chewbacca. In fact, I thought it was great that we finally got to go there & see what the Planet is like (Kashykk was originally intended to be the scene of the final battle in Return of the Jedi, but Lucas chose to use Ewoks instead of Wookies).
Have you noticed that there's not a single new character on any of the promos for this movie? No Anakin, no young Obi-Wan, etc. Its all the old recycled characters. Watch the Chewbacca Cingular commercial: there's Chewie, Vader, the Droids, Yoda, & STORM Troopers (not CLONE Troopers) in the spot.
I could hear the meeting now with the Pepsi/Cingular people & Lucas: we'll take all the old characters, but I don't want fucking Jar-Jar's face anywhere near our product.
"I figured he'd make a connection in Episode III but he failed there as well."
We didn't even get a close up of Tarkin in this movie. Its a far away shot with a smudged lens of a guy made up to look like Tarkin.
