>>3592Yeah it's not bad, it just pales in comparison with how fucking good the rest is.
The premise itself might also alienate some too, since it's basically just a treasure hunt. It's almost irrelevant for the enjoyment, because what makes GK great and what the series is focusing on are the characters, dynamics, character developments and the action/comedy combo that should be a treat to everybody that likes classic western, action or slap-stick movies. Thing is just that manga fans that haven't read it don't know that yet.
The other problem is probably the anime adaption. Most people choose the anime if they want to get into something that has both and because of the CGI bear, the mediocre animation and the fucked pacing the anime gives off a bad impression. I myself postponed the series for years after watching s1 and only considering it a 6/10 "great premise and characters but badly executed, not sure if fault of the anime or manga too".
I recommended the series to a few people and all of them watched it instead of reading it and told me it wasn't that good and gave up on it.
