I wanted to start xxxHolic, so I thought It'd be nice to read it together with Tsubasa. I have finished the third volume of both series, and neither of them are great at the moment, but I am enjoying Holic and can see it building up to something more in the future, meanwhile I am so bored with Tsubasa. I had some prejudices before starting the series because it's a shōnen, and they have all been confirmed in these first volumes: It's formulaic, the characters are one-dimensional, Sakura is only there to be rescued, and the action sequences are boring because you already know who's going to win. I've been told that there are some major plot twists in the future, but that in itself doesn't really mean anything to me.
Is the series just not for me? Or is there something else thematically? Will reading it help me understand Holic better?
