I'll read or watch anything. Romance is my favorite genre. Action, sports, fantasy, futuristic...all of it is good. I don't care how old or new something is; animation style will not dissuade me from watching something. Of course I do enjoy beautiful animation. Redline was stunning. Endings are the most important part of anime and manga, to me at least. If everything was nearly perfect, but the ending was awful (left things too unresolved, choosing the wrong love interest, wrong characters dying, etc), then I will most likely rate the anime or manga as ½ a star. What else am I reasonably supposed to do when you give me something like the ending of Berserk? Plus everyone ignoring Griffith’s narcissistic personality and thinking he was actually a good guy worthy of following upset me. But even that is relatively minor compared to leaving the viewer with that massacre of an ending. I still enjoy Berserk though; I will watch it again occasionally just to experience the whirlwind of emotions it elicits.
And to close, two of the greatest mangakas of all time: Mitsuru Adachi and Kouji Seo. I love almost everything they create, even the rollercoaster ride of highs and lows that will inevitably be part of their stories.
