Finished Monday, in fact. I’m not disappointed. I’ve read a couple of reviews that compare books 4 and 5 to Empire Strikes Back.
I’d have to agree. Darker turns, more psychological, and the good guys don’t “win” so much as “get away.”
The only thing is, I hope that Rowling doesn’t resort to an army of House Elves to overthrow the Death Eaters and save the day, a la the Ewoks in Return of the Jedi.
