That whole post seems to me to draw a parallel between Jar Jar's deeper storyline and George Lucas's script writing. George's fumbling attempts at putting together a good script/story 20 years after his prime are much like Jar Jar's character/battle scenes/story arc. They're both sad and pathetic and such a colossal fuck up that you can't help but to look for a deeper meaning in an attempt to explain the cataclysm that permanently tainted a beloved fictional universe originally shaped by exceptional storytelling and cutting edge special effects.
Everything I've read about George Lucas suggests he's out of his mind, and should be court ordered not to touch anything star wars related ever again. At least it's in Disney's hands now.
