The only set I've been impressed with is Diagon Alley, which I did about a month ago and which was the best thing I've built ever.
So the Knight Bus redo looks worse than the original, the Forbidden Forest might be a good run for the money considering Hagrid, Voldemort, Narcissa, and blue flames being rare things, the Battle looks cool, especially because of Death Eater, Sprout, Neville, and Lupin.
So yeah, it looks like after those, nothing's going to come out seeing as either WB will take license, or Lego will think people will lose interest in the theme (I never will! ). Which makes me super sad.
