I kind of agree. I didn't want to watch this show but my little brothers did so I got hooked but the 1st few episodes had Reborn making a hell out of Tsuna's life and I got annoyed. I didn't like him before and I don't think I will like him as much since he's still annoying.
Also, 5-year old Lambo... he's annoying. And Haru cause she's too possessive of Tsuna and that attitude goes from just possessive to just annoying.
I hated the Tsuna at the 1st few episodes cause unlike other anime main characters, he needed a bullet to make him courageous and stronger but I liked him after a while when he doesn't act to wimpy anymore.
