Kiseijuu... Beck...
Vagabond I loved, but then I just started to despise some of the characters. Like Musashi's childhood friend "Kojiro". And the fact that the story follows Otsu quite a bit, but I have a sinking suspicion that she'll end up with some other guy (Considering Musashi never married in real life... Though it is a -fictional- retelling... But I dunno if I want to get my hopes up
). So I haven't been able to get myself to read that for a while.
Uhh... Historie is amazing in the way that its told... And Vinland Saga is shaping up to be interesting.
Want to read more of Aflame Inferno, but that only started getting translated again recently.
Humm... Death Note got repetitive after the first half. If it had ended before then, it would've been deserving.
Slam Dunk... The main character is just sooo retarded, I can't get myself into it. Maybe its the way he looks, but everything about him rings stupidity. If the protagonist had been his rival, maybe I could have gotten into that. But unless the idiot shapes up later on in the manga, there's no way i could ever read it.
Great Teacher Onizuka is the only manga i was ever able to enjoy that didn't have an overarching plot that stood out.
Sanctuary was remarkable.
