Saw the movie last night. I thought it was the best of the prequels and got me to pop Episode 4 in this morning thanks to that last scene. It really does hammer the point home that Luke is the last hope for the Jedis.
Ian MacDarmid's portrayal of the Emperor has always been in a ball and he seems to be absolutely reveling in it in this movie. I can totally see why Anakin sided with him. I mean, didn't the Jedi just come off as sanctimonious bastards or what? He foresees his wife's death, and all they tell him is to let go of all emotional attachments. Whatever.
On a related note, I think my girlfriend may be tired of my "Talk Like the Evil Emperor Day" schtick.
