They're not terrible, but they're not anything special either. Very matter-of-fact. Yup, the Empire does indeed strike back in the second movie - no argument there.
Lucas would've probably called Blade Runner something along the lines of The Hunt for Androids. Which is the better title, I ask you? :)
Good point. The titles are quite literal. But I guess it had something to do with the B-movie serial thing Lucas had going. Blade Runner is better, but I would love to see The Hunt for Androids.
