In addition to Bioman's first two episodes, I also watched Maskman's first 4 episodes. Like with Bioman, I normally wouldn't do this since its not a currently airing show but man did it give me a lot to talk about. Lets get right into it.
One thing that really surprised me was when they were training to unlock Aura Power in episode 3. Takeru got distracted because he was thinking about Mio during meditation. That caused an energy feedback that threw them all over a cliff and no one tried to punch him for messing up. I'm not even kidding, I expected Kenta to slug him once they got back on their feet. Its a sad thing that I'm just so used to modern styles that I instinctively expected the heroes to be jerks to each other early on. Heck they even followed Takeru when they heard Mio's voice. It was really rather refreshing to see. It really shows solidarity in the team and that everyone understands what Takeru is going through. The training itself was nice to see. I'm always a sucker for training montages.
