Episode 5 just lacked the charming atmosphere that most of the first episodes of the anime and the manga have. It was... dry. They made Seiji too sweet, too soon, Ayase went from bitch to giggly school girl with as close to no actual segue as humanly possible, and Midori... well, I never really liked Midori all that much, anyway, but I still don't like her in the anime.
