Sidious 'disappointed' with Anakin/Vader?
That star wars databank book sure is great. I like the factbox about Grevious it says he has four arms and then the other fact is that he is secretly humiliated that they brought him back. What a pairing of facts!
Anyway, it also says that Vader wasn't what Palpatine was expecting (I suppose he isn't as agile and cool as Maul), is this actually true though, I mean does it mention this in other sources?
