Sure, he’s cute, but the flaws in his design are obvious the first time he approaches anything but the shallowest of stairs. Also: He has jets, a periscope, a taser and oil canisters to make enforcer droids fall about in slapsticky fashion — and no voice synthesizer. Imagine that design conversation: “Yes, we can afford slapstick oil and tasers, but we’ll never get a 30-cent voice chip past accounting. That’s just madness.”
Can’t fully extend his arms; has a bunch of exposed wiring in his abs; walks and runs as if he has the droid equivalent of arthritis. And you say, well, he was put together by an eight-year-old. Yes, but a trip to the nearest Radio Shack would fix that. Also, I’m still waiting to hear the rationale for making a protocol droid a shrieking coward, aside from George Lucas rummaging through a box of offensive stereotypes (which he’d later return to while building Jar-Jar Binks) and picking out the “mincing gay man” module.
