Well, here's an idea for a question, regarding the Failure 5 (Saiyuki, Yui, Taisei, Beast, Shinobi), what do you think could've been done that might've saved the series? Curious what people might think.
Saiyuki:
The very beginning (chapters 1-3~) was excellent. What wrecked the series' chances was the introduction of the main villain so early and having that pointless early fight with him (which also unlocked the protags super-mode and immediate cancellation vibes). Cut that, trim down the exposition and get to the introduction of the side characters & the first proper arc earlier (chapter 7~). Better explain those deeper concepts during missions when you have clear examples and some personal stakes.
Make sure to keep the possibility to introduce more interesting power variations later instead of limiting yourself to "reshape staff" and "physical enhancement" by definition.
Yui:
Idk, the series was deeply conceptually flawed, even if a few early chapters were fun. Maybe have White Yui be less painfully boring and the male lead more likable? I honestly would've preferred if the series was more of a female delinquent series and 90% about Black Yui. Dropped it too early to say more about the genre shift.
Tbh, going heavier for the 90s-style fanservice from ch1 could have also helped its popularity, cuz the artstyle is quite good.
Beast:
I still see a chance that it could recover, and it honestly did a lot of things rather well. Main problems might again be that it takes way too long to properly introduce the team and has the main lead have such an unoriginal specialty. Also, I personally was very annoyed by HOW the team was first introduced (super skilled but uncoordinated without their leader)... it didn't make them come of as a team I'd wanna follow.
TSS:
Honestly... not exist?
Cut the nationalism, cut the godawful basic popculture references, completely rewrite the lead and his tigerman-lancer, define their powers&limitations better, learn how to properly structure action scenes, take stuff more seriously in general if you wanna do an urban scifi-series...
As mentioned, I'm now enjoying it for it's ridiculous badness, but I'm not sure if that will improve it's rankings. It sure as heck doesn't make it a legit good series.
