Love: Darth Vader, Darth Maul, Light-sabers, the whole "force" thing, all the space-craft, the music, Chewie, hell even the goddamn ewoks!
Hate: Everything from the prequel trilogy (barring Darth Maul....died waaay too soon), I hate R2-D2 & C3PO....AND Yoda! I have since I was a small child.
It's mainly all the new stuff. It should have been left as the phenomenom of it's time, not whored on by Lucas for the braindead children of today and money he doesn't need. I still feel though, that the original trilogy is vital viewing for all children....great story-telling, fantasy and imagination.
