I only managed to watch 30 episodes of this(around the part with the floating head nazi being introduced) out of 90 episodes, so being repetitive is a given, really.
I'm guessing Sayaka and Kouji's little brother. Surely you can't mean Boss, the guy's a fucking champion.
Now you gotta watch Testujin or Giant Robo. In the latter case, the OVA is more of a medley of Yokoyama's works than an adaptation proper. For that you'll probably have to sit through the unsubbed 2007 anniversary anime.
Nah Boss was great. I was thinking more of Sayaka, Shiro, and even Koji now and then.
I've seen part of the Tetsujin and Giant Robo OVAs, I was impressed by what I saw. Guess I'll hunt them down next
Finished the Giant Robo OVA. Loved the operatic score complimenting the action and mecha design, though I felt the writing was kind of all over the place
Tetsujin-28 is next
