Technology Issues
One of my main gripes with the prequel trilogy, is GL's plan to have the technology from the Prequel Trilogy transition between EI and EIII to show a progression to the technology in the Original Trilogy.
For example, In EPII, we see all sorts of rocket and missle technology used. In EIII, we see that this rocket technology is to be replaced by "proton torpedos" such as the one luke uses in EIV to destory the first death star.
Now, in my opinion, that is just plain stupid. Imagine, you have a GALACTIC CIVILIZATION that uses laser blasters, lightsabers, and faster than light travel, yet we are supposed to beleive they are still using unguided/guided ROCKETS?!?! and all of a sudden, during the 40 or so year period these movies cover, technology changes drastically?! When its been around for 1000 generations, you'd think they would have thought of those things beforehand, especially in light of the other technologies present.
Basically, GL has raped the "universe" with the OT. Technology from the OT should have been EXACTLY the same as the PT. when a civilization has been around for tens of thousands of years, things dont just dramatically change in 40 years.
