This is the best thing I've seen on the internet in a while.
George Lucas is an easy target, but Mike Stoklasa (in character here as Mr. Plinkett) manages to be equally funny and intelligent in this review. The knowledge dropped (especially in part 3) was a welcomed surprise.
I've only recently discovered this site, but he's also reviewed The Phantom Menace, and Attack of the Clones. A perfect way to kill a couple of hours.
