Review of Case File nº221: Kabukicho
I don't think this anime has such a low score and I'll try to defend very briefly why. You may think it has many comic reliefs, it's superficial, doesn't look too dark or mysterious. I'm not gonna lie, that's how it goes in the first quarter. I suggest to continue on and watch more than the first 6 chapters (or 3, like some do. Very bad idea, guys. You don't know what you're missing on). You can't expect to watch an exact copy of the original novels as it isn't an American production like "Supernatural" or "Blade": It's a reformulation of Sherlock Holmes in a futuristicconcept but the gist of it it's actually the same. I can vouch you won't be dissapointed later on when you start to see how deep and dark it'll become as chapters go on.
If you still think it's a rip-off from Sherlock Holmes, why are you even watching it? I'm a Sherlock fan since many years ago and I don't mind watching the different adaptations people may offer.
