Star Wars Design Sucks

AMCTV.com brings us John Scalzi’s Guide to the Most Epic FAILs in Star Wars Design. Here’s the blurb on the Death Star:

An unshielded exhaust port leading directly to the central reactor? Really? And when you rebuild it, your solution to this problem is four paths into the central core so large that you can literally fly a spaceship through them? Brilliant. Note to the Emperor: Someone on your Death Star design staff is in the pay of Rebel forces. Oh, right, you can’t get the memo because someone threw you down a huge exposed shaft in your Death Star throne room.

What do you think, Fivers? Is Scalzi just being crotchety and anti-Lucas or something, or does he have a point?
