Two part story arcs in the heisei era go all the way back to Kamen Rider Kuuga. But if he means ditching the two episode format as an overused crutch, then I'm fine with it. I don't nessicarily hate the two episode storyline format unless its something really story based like an Ultimate form (Wizard needed 3 episodes for the Infinity upgrade storyline). I like how Ryuki and Kabuto did thier story arcs, Ryuki's two episode stroyline format mostly only applied to the Mirror Monsters Shinji and Ren fought. Even then, later on, the Mirror monsters weren't the focus of the episodes. I'm only on episode 10 of Kabuto but from what I've seen, its been episodic and had a four episode storyline based on Thebee broken into two parts.

As for being "darker", after seeing the "darker" heisei series and seeing newer stuff like W, OOO and Wizard. Darker just means the ratio of serious characters to nonserious and how often death occours. Its not really that much that makes it different. Now if you showed me one of the gruesome deaths jn Agito I hear about I'll probably change my mind but still.
