Truth be told, this chapter was pretty bad. It's interesting to see all the changes Oda eventually made to the series, especially with Garp but clearly every change Oda made was for the better. Honestly though, I never really liked the beginning of One Piece anyway. The Shanks backstory part was cool but the content outside of that wasn't really good in my opinion.
Overall, I'm glad I read Wanted! I'd rank the stories (from best to worst) like this . . .
I. God's Gift for the Future
II. Monsters
III. Wanted!
IV. Romance Dawn
V. Itsuki yakou
With the first three being worth a read, particular God's Gift. Really loved that one, the other two were enjoyable but there was something special about God's Gift.
