I had trouble with the Emperor's appearance. It seems to me the make up was better 20 years ago when he was younger than his appearance now. I mean I am a devoted Star Wars fan and I liked the movie but the Emperor didn't look right and I thought Anakin was too quick to give in.
Edit: oh and Narf I must ask, as we do on Games Workshop forums when someone makes your mistake, who's the Emporer, some bloke who sells things
