And I dig all the Clone Wars covers I've ever seen (really like the side-by-side with the connecting spine picture)... except for the official one-- it's just kinda blah.
The thing I dislike most about the official prequel logos/posters is the focus not being on the title of the movie, but on its Episode number, which was then continued on the OT box set. It's almost disrespect for the fact the movies have actual titles. I'd love to see the ROTJ-like Sith logo on a cover, which was on t-shirts a while back. And I believe included in a slipcase on the UK release of the Sith soundtrack-- and it looks awesome.
Another peeve is the fact that Hayden Christensen looks exactly like Thomas Haden Church (Sideways, TV's "Wings") on the Sith poster artwork. Thomas Ha(y)den Christ(Church)ensen. Conspiracy? I think so.
