You're not alone. I was also fairly disappointed in haphazard manner of the last 10-15 minutes. The last 4 episodes also seemed quite draggy, compared with the storytelling of the rest of the show before. As for the crosswalk scene: After thinking anxiously that Lawyer Ahn was going to do something ridiculous and out-of-character, such as dirtying his own hands, I was certain that the slow-motion crossing of the street would end disastrously.. such as, an Ahn-driven truck of doom? I didn't expect him to try stabbing! But the post-walk around smooching scene had me fairly convinced that Ahn had maybe been foiled in his attempt? As in, Maru seeing him was enough for him to chicken out and not draw an actual knife? I couldn't believe they did all that After Maru was apparently stabbed in the side! Seriously! And.. then to have all that ultimately come to nought? Too weird. Oh well, I live in a world when NG was a fabulous watch each week, and I will try and ignore the actual written ending.. It's just fiction right? I can rewrite it however I want in my own little world.. :p
