I intially read Lupin III Greatest Heist and after greatly enjoying that I thought I should go read the original manga. However there was a problem. A problem that still persist 1/3rd of the way in (I have now read the whole thing and it continues the whole way throughout.) I can't fucking tell what's going on. Ever. While the art is genuinely phenominal the pacing and clarity is absolutely abysmal. After reading most chapters if you put a gun to my head and said, "Explain what happened and how Lupin stole the thing." I would be dead9 times out of 10. I'm not referring to the episodic nature of the manga either I really like episodic manga.
I also haven't mentioned the rampent sexism in the manga where every woman in the book follows the Madonna/Whore trope and it's pretty fucking gross. I can enjoy problamatic media but goddamn. I'll give Shin Lupin a try but if it suffers the same problems I'll drop it just as quickly.
