I started watching anime and started reading manga, for one because I caught to One Piece and I wanted to read the manga to see what was happening in Wano and I can' t wait 50+ episodes for the the main important part of the arc to start. I also wanted to read manga because I had a friend who was telling me about all this great manga he was reading and it sounded interesting and I started reading Promised Neverland before it had an animation, it was the first one I read and it was really interesting. But I can agree action genres are hard to read sometimes I have to reread a few panels sometimes to make sure I know what's happening.
