Nicely done. The way he keeps referencing the guy responsible with nicknames reminds me of a time I added subtitles to Robin Hood so every instance of the name came subbed as "Kevin 'Dances With Wolves' Costner" (the exact movie referenced changed each time).

People will complain. They always did. It'll just be more apparent now. But then, so will the praise.

As for spoilers, I've found various fandoms are very good at keeping a lid on those...So maybe.
