1.) Artificial Enemy
This episode established that Shaft was animating it a bit more than it needed. (They even put the hand there.) Also - as most animes do - it differs from the manga and songs. It puts in Ayano and Shintaro scenes, and changes Shintaro's room from a small room to a gigantic one, complete with a big window. It also changes his computer from a regular size to an enormous screen, gives the terrorists freaky Joker masks, and throws Seto into the terrorist scene just for the fun of it.
