I tried to understand why dextrannies twitter shitters have a hate boner with Masuda.
So I went back and looked up masuda involvement in the previous games, turns out what Masuda does is overall game design, theme and art design and a lot of soundtrack.
Not only for games buy as well for the movies.
His directing role has nothing to do with personal, code or technical stuff, and the few times he coded was related to music and sound effect related.
After watching the treehouse video, I realized deranged dextrannies hate him because he was the one to respond the interviewer question about the Dex shit.
All the technical shit is literally the fault of the production management, Ohmori (director and developer) and Tajiri (Game Freak's CEO and executive producer).
