I am 4 eps in and am still not feeling this show.. Mob is kinda dull and the side characters aren't really any better so far. Especially the blonde office guy who seems like an exploitative jerk.
That's his character at the start. He is "boring" and somewhat purposefully so because of things that have happened in the past. He doesn't stand out and is trying to figure out exactly who he is without relying on his psychic powers as he considers that a crutch for the weak willed or selfish.
Also Reigen is a con man but one with a heart of gold who really believes his own hype.
