I've got some problems with the pacing of 9 and 10, because they both feel like they drag on. Kind of a holdover from the manga chapters, though. They could have easily fit both episodes into about 1 1/2 and started up the efforts to retake Trost in the remaining time.
edit: okay some people across the internets are ragging on this episode -really- hard, and it's difficult to not feel defensive about a series I love, but my hopes for the anime feel considerably lowered after 9+10, not to mention 14 is gonna be a recap episode. I really hope Wit can get out of this hole they're in, both pacing-wise and budget-wise. I never watched more than 7 episodes of Death Note, and I never even bothered with Guilty Crown, so I have no idea what expectations I should place on director Araki with Titan.
