Star Wars, Empire get 10s across the board. Jedi gets deductions each for blah visuals and makeup (I consider the ewoks merely a poor creature effect) and some bad line readings (or just bad looping). 10, 10, 8 for the trilogy.
Phantom Menace, Clones, Sith get all 5s and 6s. except for Ewan /Obi-Wan who is awesome. I have no idea how to score that...
